Ouch! Pain in the Neck?


Oh! Pain in the Neck?!

Neck pain, at times, can become pain in the neck’ quite literally. People who have experienced neck pain alone know how painful the neck pain can turnout to be.

Neck is one of the most flexible regions of the spine, which consists of vertebrae, seven shock absorbing discs, muscles, and vertebral ligaments to hold them in place. The uppermost cervical disc connects the top of the spinal column to the base of the skull. The spinal cord, which sends nerve impulses to every part of the body, runs through a canal in the cervical vertebrae and continues all the way down the spine.

What Causes neck pain?

Most people experience neck pain at some point in their lives. Neck pain can be acute, lasting for few hours or a few weeks, or it can be chronic. Neck pain that lasts several weeks or longer is considered chronic neck pain.

Neck pain can be caused by an activity or injury or by a medical condition. Your head and neck region is vulnerable to many different stresses. Bad posture can cause misalignment of your neck, head, and spine. Car accidents can cause whiplash. Age and wear and tear can cause arthritis. Even activities such as chewing gum and reading in bed and cause pain. How do we avoid these potential problems? And if we can’t avoid them, how can we recover as quickly as possible.

Non-specific neck pain

Many people develop a stiff and painful neck for no obvious reason. It may happen after a minor twisting injury, for example while gardening. Since the underlying cause for this type of neck pain is not fully understood hence it is called ‘non-specific neck pain’ Having non-specific neck pain does not mean that your neck is damaged. Often it happens in people whose necks would appear completely normal under an x-ray. It is the most common type of neck pain and disappears after a few days.

Activities that cause neck pain

Neck pain mostly is caused by activities that result in repeated or prolonged movements of the neck’s muscles, ligaments, tendons, bones, or joints. This can result in a strain(an overstretched or overused muscle), a sprain (injury to a ligament), a spasm of the neck muscles, or inflammation of the neck joints.

           1. Holding your head in a forward or odd position for long periods of time

               while working, reading, watching TV, or talking on the telephone.

           2. Sleeping on a pillow that is too high or too flat or doesn’t adequately 

               support your head, or sleeping on your stomach with your neck twisted

               or bent.

           3. Spending long periods of time resting your forehead on your upright fist

               or arm.

           4. Work that uses the upper body and arms, such as painting a ceiling or 

               other overhead work.

Injuries that cause neck pain

The Spine consists of interlocking bones(vertebrae) and discs that separate the vertebrae. The portion of the spine that runs through the neck is known as the cervical spine. Muscles and ligaments in the neck hold the cervical spine together. Injury to any of these structures may result in neck pain.

Minor injuries may occur from tripping or from excessive motion of the cervical spine. Severe neck injuries may occur from whiplash in an accident, falls from significant heights, direct blows to the face or the back or top of the head, sports-related injuries , a penetrating injury such as a stab wound, or pressure applied to the outside of the neck, such as strangulation.

Pain from an injury may be sudden and severe. Bruising and swelling may develop soon after the injury. Sudden (acute) injuries can result in strain and pain in the neck, dislocation of the spin, or a ruptured disc.

Medical conditions that cause neck pain 

                  1. Neck pain may be caused by or related to medical conditions such as:

                  2. Cervical Spinal Stenosis

                  3. Cervical Spondylosis

                  4. Illnesses, such as meningitis, which cause inflammation around the

                      tissues of the brain and spinal cord.

                  5.Chronic conditions such as fibromyalgia, rheumatoid arthritis, or

                     ankylosing spondylitis

Torticollis (wryneck): Torticollis is

caused by severe muscle tightness or a shortened muscle on

one side of the neck, causing the head to be tilted to one side.

Referred pain: Referred pain occurs when

a problem in one place in the body causes pain in another

place. For example, a problem with your jaw or your heart can

cause neck pain.

Infection or a tumor in the neck area.

Signs and Symptoms

Neck pain takes many forms. Signs and symptoms of neck pain may include:

           1. Pain in your neck that may be sharp or dull

           2. Stiffness in your neck

           3. Difficulty going about your daily tasks because of pain or stiffness in

               your neck

           4. Shoulder pain in addition to neck pain, in some cases

           5. Back pain in addition to neck pain, in some cases

Help yourself to prevent neck pain

Take frequent breaks: Don’t sit in one place for a long time, such as your car or at your desk.

Arrange some of the items in your office that cause inconvenience. This will force you to get up, stretch or walk around.

Maintain good neck posture:

Adjust the seat of your computer or desk chair so that your hips are slightly higher than your knees. Your head and neck will naturally follow in the correct position. While traveling in a car, airplane or train, place a small pillow or rolled towel between your neck and a head rest to keep the normal curve in your neck.

Avoid too many pillows:

Avoid sleeping with too many pillows or falling asleep in front of the television with your head on the arm of a couch.

Exercise: Treat your body to a consistent regimen of stretching and strengthening to balance your muscle groups. This protects your neck as well as helping your whole body. Walking at any pace is excellent exercise for your neck. The rotation of the spine provides a great natural workout for the neck muscles.

Eat smart and Drink water:

Good nutrition and staying well hydrated are not only important to stay healthy, but vital in the healing process.

How To Lose Weight From A Low Carbohydrate Diet Plan


With the sudden boom of dieting in the country, different diet programs have been introduced in the country. Although many experts believe that proper exercise and not only diet can lose those pounds in a healthy way, many people still believe in the power of diet programs and diet plans. One of the most controversial kinds of diet plans is the low-carbohydrate diet program, which focuses on the reduction of carbohydrate consumption in the body.

According to the theory, when carbohydrates are no longer being taken in, the body will be forced to use fats and water as alternative sources of energy; thereby helping to shed off those unwanted pounds.

Fats, unbeknownst to many, can actually be converted to energy. The body just doesn’t use it as the first priority because it is more complex in structure and therefore, harder to break down and convert into energy. Among the popular low carbohydrate diets in the country is the Atkins diet.

Despite arguments from its critics, low carbohydrate diet has proven its effectiveness in terms of losing that extra weight. To date, it counts millions of followers not only in the country but also outside America.

Actually, cutting down on carbohydrates in the diet is a practice that people have been doing for years. When people cut down on their rice or bread or do not eat rice at all, they are reducing their carbohydrate intake. Of course, because it is not an official diet plan they are not really restricting themselves completely. When you are under a diet plan, you are not allowed to eat any kind of carbohydrates.

One of the advantages of low carbohydrate diet is the fact that it can actually increase the levels of good cholesterol in the body. This is really good news to people who have a heart problem. This is perhaps the reason why Atkins diet was used for cardio patients. This diet plan can also reduce the amount of triglycerides in the body. Triglycerides can be dangerous when combined with a high level of LDL or bad cholesterol. Both can increase the risk for heart attack and heart disease.

Low carb diet plans are also found to be good in balancing mood swings. They will not be prone to extreme lows such as depression or extreme high. People who are under the program are found to have fairly stable energy levels unlike those with high carbo levels.

LOW CARB DIET 101

Indeed, a lot has been said about various diets and how these work for some people. There’ s the Atkins Diet, the South Beach, the After-Six Diet plan and so on goes on the list of diet crazes that swept the western world and even Asian regions. Among all these, one type of diet has become popular than the others it’s called the Low Carb Diet.

Basically, low carb diet actually emphasizes cutting down on from a person’s daily food intake. This diet allows the dieter to take in all foods except those that have carbohydrates. Although there are many testimonies that prove that low carb diet really works, you must be very knowledgeable first about its pros and cons before deciding to go with the hype.

People who have tried low carb diets say that its advantages include:

1. Faster and quicker weight loss compared to fasting.

2. The diet may result to higher protein intake and absorption.

3. It stabilizes blood sugar levels and is extremely beneficial to those who suffer from diabetics.

Experts say that the disadvantages of low carb diets may include:

- High cholesterol levels due to the lack of protein-rich and fatty foods that has saturated fats.

- Increased blood pressure due to elimination of whole grains products that help lower blood pressure.

- It can lead to osteoporosis because there will be no enough supply of calcium.

- In some cases, this diet can lead to diarrhea, constipation, and severe headaches.

- Low carb diets increase the possibility of lower mental acuity.

- Instead of losing weight, this diet can lead to weight gain.

If you are planning on taking low carb diet, here are some helpful tips to keep you in track:

1. Make sure to drink lots of water to avoid dehydration and constipation.

2. Consider taking in more fiber and vitamin supplements.

3. Cease from consuming products that has sugar.

4. Cut down on taking in products that contain caffeine.

5. Monitor your daily carbohydrate intake.

6. Don’t mind calories, they are allowed in this diet.

7. Acquire a carbohydrate counter to keep you updated.

8. Do regular physical activities and exercise to reach ketosis easily.

9. Brace yourself for diarrhea that may last for a couple of days.

10. If possible, avoid eating foods that have saturated fats.

Back Pain – SI Joint Dysfunction


 

Sacroiliac joint pain

 Sacroiliac (SI) joint pain has gained a lot of attention in the last ten years as an underappreciated cause of back pain with some studies indicating it is responsible for 15% to 40% of low back pain. The increased attention is due to the increasing knowledge of the SI joints intimate role in pelvic stability.  I hope more physicians consider SI joint pain in their differential after reading this article.

Pathophysiology

SI joint dysfunction due to inflammation within the joint itself is called sacroilitis. Pain from within the SI joint is common in rheumatoid patients and spondyloarthropathies.

The other cause of SI joint dysfunction stems from instability of the SI joint.  Many experts feel that SI joint pain is a component of a larger problem of pelvic instability (1). Pelvic instability has traditionally been underappreciated as a cause of low back pain, buttock pain, groin pain, and leg pain. Physical therapists and doctors of osteopathic medicine have been teaching these concepts for years but only relatively recently has this dissemination of knowledge trended towards mainstream thinking among medical doctors.

The SI joint complex (the SI joint and its associated ligaments) is the major support structure of the pelvic ring and is the strongest ligament complex in the body.  The complex consists of interosseous sacroiliac ligaments, iliolumbar ligaments, posterior sacroiliac ligaments, and the sacrotuberous and sacrospinous ligaments. The SI joints are two of the three joints involved in the stability of the pelvic ring.  The pelvic ring is the meeting place of the force vectors from the upper body and the lower extremities.  The third joint in the pelvic ring is the pubis symphysis. Pelvic instability causes pelvic rotation which can also cause twisting of the pubis symphysis.  Coupling this with its anterior location appears to provide an explanation as to why patients with SI joint instability can also experience anterior groin pain. Anecdotal evidence for this is seen when patients undergo a successful SI joint intra-articular injection relieving all of their posterior back, buttock, and leg symptoms but the patient still has groin pain. Groin pain is almost never eliminated by SI joint injections unless pelvic symmetry is corrected.

 If the SI joints are unstable, it can lead to significant pain and discomfort over the SI joints as well as numerous referred areas.  If an individual affected by SI joint pain has pain only over his or her SI joint, he/she  should be considered lucky. Most often SI joint instability causes unnatural strain on the entire low back and pelvic region causing a sometimes confusing clinical picture. Pain referral patterns of SI joint pain are often confused with L5 or S1 radiculitis or radiculopathies.

Referral patterns of SI joint dysfunction (2)

SI joint dysfunction often presents with a confusing clinical presentation.

1.       Buttock pain 94%

2.       Lower lumbar pain 74%,

3.       Lower extremity pain 50%, with 28% of these lower extremity pains going distal to the knee

4.       Pain goes all the way into the foot 13%. Younger patients are more likely to refer pain distal to the knee.

5.       Groin pain 14%. 

Most patients with SI joint instability also experience pain over the buttock region due to secondary muscle spasm of the gluteus muscles and piriformis complex.  Lower extremity symptoms are explained by the piriformis muscles natural tendency to spasm or tighten over the sciatic nerve whenever the SI joint is out of alignment.  This spasm of gluteus and piriformis muscles can cause a mechanical crowding or impingement of the sciatic nerve as it exits just below the SI joint (see figure 1. note the intimate association of the piriformis muscle, SI joint, and sciatic nerve).  Patients often complain of buttock pain and radiation of pain down to the knee and even down to the foot. Not all back pain and leg pains are due to a pinched a nerve from an intervertebral disk herniation.  SI joint dysfunction very closely mimics S1 or L5 radiculitis’ or radiculopathies because of the above described sciatic nerve irritation or impingement.

Groin pain and abdominal pain are not uncommon with SI joint instability.  Often times the groin pain is mistaken as a urologic problem like pudendal neuralgia, prostatitis,  genitofemoral neuralgia, or sterile epidydymitis(1). This is likely either due to unnatural tension on the nerves and ligaments around the pubis symphysis or actual impingement of the pudendal nerve which lies between the sacrospinous ligament and sacrotuberous ligament. The distance between these two ligaments abruptly narrows when the Ilium and sacrum are out of alignment i.e. SI joint instability.

The typical history of SI joint dysfunction consists of lateral or bilateral low back pain almost always below the pelvic rim. Pain can also radiate into the hip, groin, pelvis, leg, and foot.  The most common location of pain is in the buttock with pain extending down to the knee. Females are much more affected than males though the ratio is unclear.  The mechanism of injury is a continuum from completely atraumatic events to more obvious trauma like motor vehicle accidents, childbirth, or falls. A little over one third of failed back surgery patients suffer from SI joint dysfunction. In my practice, I often see patients who lose a substantial amount of weight and then develop SI joint dysfunction.  The etiology of this is unclear. Women who have had multiple births also seem to have a higher incidence of SI joint dysfunction.  The symptoms may be acute or may present as a remote or cumulative injury with chronic waxing and waning of symptoms with slow progression over time.  Patients often experience some degree of temporary relief with manipulation.  Patients must change positions frequently to avoid pain.  This is called “Theater Party Cocktail Syndrome”. Patient’s legs can also feel like they’re going to give out, but with objective testing of motor strength, no dysfunction is found. This is called a “Slipping Crutch syndrome”. Patients usually have a difficult time sleeping and getting out of bed in the morning can be excruciatingly painful. Continued movement after waking up tends to improve the pain.

There are many provocative physical exam maneuvers used to help establish the diagnosis of SI joint dysfunction. Going through each one of these provocative maneuvers is beyond the scope of this article.  It is important to note that the predictive value of provocative SI joint maneuvers in determining SI joint dysfunction is only 60%(4).  The conclusion of a recent study by Slipman et al(5), was that physical exam techniques can at best enter SI joint dysfunction into the differential diagnosis of a patient’s low back pain.  Of the alleged signs of sacroiliac joint pain, maximum pain below L5 coupled with pointing to the PSIS or local tenderness just medial to the PSIS (sacral sulcus) has the highest positive predictive value (PPD) at 60%(4).

Diagnosis

The gold standard for making a diagnosis of SI joint dysfunction is a fluoroscopically guided SI joint injection. Fluoroscopy is needed to accurately and consistently inject the sacroiliac joint.  Only 12% of patients had intra-articular SI joint injections when fluoroscopy was not utilized (3).  Also important is to anesthetize the entire SI joint complex.  In my experience as an interventional pain physician this cannot be consistently done by palpation alone, especially in obese patients.  It is humbling to see anatomy change under fluoroscopic guidance. What you perceive with palpation is sometimes markedly different than the actual location of the structure that you palpate.  Also vitally important is that these diagnostic injections are followed up with another physical exam while the patient is in the recovery room. Sending a patient home, having them follow up in several weeks, and then determining if this “diagnostic” injection was successful has consistently been shown to be an inaccurate way of establishing a pathoanatomic diagnosis.

Treatments

There is no one specific treatment for SI joint dysfunction which helps all patients.  The treatment varies if the dysfunction is intra-articular (inflammatory), or if it’s a lack of stability. Conservative treatment should first be tried including the manipulation by a qualified physical therapist or osteopathic physician to restore normal motion and balance,  home self-correction exercises,  a walking program (avoid heavy axial loading maneuvers), and core strengthening exercises (Pilates, Yoga, or guided physical therapy). Some patients also benefit from a quality SI joint support belt.  If conservative therapy is not helpful then I recommend a diagnostic SI joint complex injection.  The injection should include the SI joint ( intra-articularly) and the supporting ligaments with pain relief lasting for the duration of the local anesthetic and achieving greater than 75% pain relief. If there is any question about the positivity of this diagnostic test,  it should be repeated.

Radiofrequency Denervation

If the diagnosis has been established by an intra-articular SI joint injection and pain relief using conservative therapy affords no long-term pain relief, then consideration for other treatments can be made.  Radiofrequency denervation of an SI joint carries about a 65% success rate for patients who have failed other conservative therapies and only mild instability around the joint. The procedure involves the neurotomy of the lateral branch nerves that lay over the sacrum and innervate the posterior SI joint. The advantage of SI joint radiofrequency is that it is a very safe procedure with almost no documented morbidity.

Prolotherapy

Another treatment for SI joint pain is Prolotherapy.  Prolotherapy works by stimulating an inflammatory cascade which leads to fibroblastic activity thereby strengthening the entheses of ligaments and tendons. Prolotherapy on SI joints usually requires very strong Prolotherapy solutions.  In my experience, hypertonic Dextrose Prolotherapy only relieves 20 to 30% of most patients’ pain.  More aggressive prolotherapy usually reduces pain by 50% or greater in roughly 75% of patients. The greatest advantage of Prolotherapy is that it is provides a level of permanent relief.

SI joint Fusion

If the patient fails radiofrequency and prolotherapy, the last treatment option would be consideration for an SI joint fusion.  The outcome data on SI joint fusions is not highly favorable.  However, there are new minimally invasive SI joint fusions that have recently been approved by the FDA that appear promising. Patients with very diffuse pelvic pain and leg pains are not good candidates for fusion surgery.
