TMJ: Temporomandibular Joint Disorders

Today's post is about a little different kind of chronic pain condition.  TMD (or TMJ), officially known as Temporomandibular Joint Disorder, affects the hinge-like joint that connects the jaw to the temporal bones of the skull.  Without this skeletal feature, life would be quite different, for it is used for chewing food, speaking, and yawning.




The cause of TMJ/TMD is unclear, but it is thought to arise as a result of whiplash or injury.  Other possible causes include grinding of the teeth, stress,  or arthritis of the temporomandibular joint. There is a cushion-like disk within this joint that may fall out of alignment, potentially leading to TMD.

This condition is more common in women, and usually affects persons between the ages of 20 and 40. Common symptoms of TMJ/TMD include clicking, popping or grating sounds when chewing or opening the mouth. Sometimes the jaw will actually lock open or closed. Facial pain, or perhaps pain in the neck or shoulders can be indicative of TMJ/TMD if they occur when chewing, speaking, or opening the mouth wide. In some instances the upper and lower teeth don't mesh together correctly, as if misaligned. Facial swelling can also be a sign of this disorder.Toothaches, headaches, dizziness and ringing of the ears have also been reported.

If TMJ/TMD is suspect, a visit to a dental professional is in order.  There are actually some dentists who actually specialize in the treatment of TMJ/TMD. The dentist may X-Ray your mouth/jaw or perhaps order a CT scan or MRI in addition to performing an oral exam in the office to assess the condition. Sometimes a dentist will refer the patient to an oral surgeon or orthodontist for further assessment or treatment.

There are many non-drug elements involved in the treatment of TMJ/TMD.  They include:
soft diet, heat, ice packs, and relaxation techniques, amongst others.  On occasion over the counter pain medications may be recommended.  In other cases, prescription drugs may be used. Traditional dental practices used in the treatment of TMJ/TMD include splint or mouth guards, crowns, bridges,and braces. Alternative treatments include TENS units, ultrasound therapy, and radio wave or laser therapy.

Surgical options are usually a last resort and  include arthroscopic surgery, arthrocentesis, and open joint surgery.

Living with Chronic pain hits the big screen!

Been to the movies lately?  Jennifer Aniston is on the big screen in a recent release titled "Cake." Her character, Claire is a victim of chronic pain...she belongs to a support group, where all of the members are coming to terms with the suicide of one of their members.  Of course, she also takes pain medication and addiction is another of her problems...and of course there's more! I guess I am writing this post just to bring readers' attention to the fact that Hollywood has become aware of the crisis that is chronic pain.  This movie is a testament to that. People that don't have to live with this kind of pain don't fully understand the whole story.  Maybe this movie will shed some light on the issues. Here is the official trailer for the movie: Sources: prweb;NorthJersey.com;YouTube

Effectiveness Of Ozone Injections Is No Longer Up In The Air

Most of us know someone who has osteoarthritis, if we don't have it ourselves.  Joint replacement surgery is a pretty common remedy when the joint becomes severely damaged and the patient is in a lot of pain.  With risk of complications from such a surgery, perhaps an alternative treatment should be tried first. One such remedy is the injection of a synthetic version of collagen(e.g. Synvisc®) into the affected joint.  This procedure restores the cushioning to a joint that has degenerated over the years. It can diminish the pain substantially and help put off joint replacement surgery for months to years.  The biggest drawback is that these products are expensive.   GoodRX , a web site that can be used to estimate the cost of medications, estimates the cost of these products to be over $1,000 each. Here's another example--and I am not sure how widely accepted this protocol has become since study authors introduced it in November 2015.  Are you r...

Fibromyalgia Week: Day 2

Tender points...click caption for WebMD animation Tender points are a unique feature of fibromaylgia.  There are 18 such points on the human body (9 pairs as shown).  Using special technique by hand or a dolorimeter, a fibromyalgia patient will experience pain in at least 11 points, and there will be at least one painful tender point in each quadrant of the body! One study found that up to 96% of fibromyalgia patients suffer from sleep disorders. It is believed that this is responsible for a deprivation of delta sleep, during which human growth hormone is produced. This hormone is essential to tissue repair. Other common problems in fibromyalgia are fatigue, concentration/memory ("fibro fog"), and depression.  There is no doubt in my mind that just enabling the patient to sleep well on a regular basis would be of great benefit! It is not uncommon for fibromyalgia patients to have coexisting conditions--some of these are lupus, disease, irritable bowel syndrom...
