Hyperreactive Brain Network May Be Cause of Chronic Pain in Fibromyalgia, Study Suggests

Fibromyalgia is one of the overlapping pain conditions with TMD. This article appeared in Fibromyalgia News Today on January 15, 2018. A new study suggests a hyperreactive brain network may be the underlying cause of chronic pain in fibromyalgia.

Dry Eye Linked to Chronic Overlapping Pain in Veteran Population

There may be a correlation between dry eye and chronic pain in the US military veteran population as is evident by a recent study. Ocular pain was most strongly associated with headaches, tension headaches, migraines, temporomandibular joint disorders, pelvic pain, central pain syndrome, and fibromyalgia in the veteran patient population.

Patients in Los Angeles or New York City Needed for Clinical Study - Comparative Study of Women Considering or Currently Receiving Botox© Injections for TMJ Pain

Are you a woman with "TMJ" pain in facial muscles, who has either: a. recently had Botox© injections for your pain or b. not had Botox© for your pain but has thought about such treatment? If either is true for you, you may qualify for an observational research study centrally administered by the NYU College of Dentistry. It is funded by the National Institutes of Health (NIH). The purpose of this study is to understand potential health risks that may be caused by treating "TMJ pain" with Botox© injections.

Why Head and Face Pain Cause More Suffering

Hate headaches? The distress you feel is not all in your -- well, head. People consistently rate pain of the head, face, eyeballs, ears and teeth as more disruptive, and more emotionally draining, than pain elsewhere in the body.

Migraine and Coronary Artery Disease: A Genetic Connection

There has long been as association between migraine headaches and vascular (blood vessel) dysfunction of some kind, underscored by epidemiological studies and other research. New evidence for a genetic connection now comes from the analysis of several large data sets of each condition based on Genome Wide Association Studies (GWAS).

Washington Post Article on TMD

  • Oct 3, 2017

The Washington Post recently featured an article on Temporomandibular Disorders. Below is an excerpt from that article and a link to the full story. 

"...It's one of the most common pain disorders, after low back pain and headache," says John Kusiak, acting deputy director of the National Institute of Dental and Craniofacial Research. "Fortunately, most first-onset cases of TMD will resolve with either no treatment or minimal care."

About 10 percent of people with TMD go on to develop long-term symptoms that affect the quality of their daily lives, Kusiak says. Experts usually define chronic TMD as consistent pain in the jaw area that lasts beyond three months, he says.

"The jaw is very important for a number of things, including how we eat, for smiling, for talking, for singing and for kissing," Kusiak says. "People may have difficulty talking, and smiling, difficulty interacting with others. As a result, they may develop emotional and psychological problems that can lead to the inability to work or communicate."

Scientists don't know what causes it, although trauma to the jaw or temporomandibular joint is a clear risk factor. Most of the time, TMD develops for no obvious reason.

Because the condition is more common in women, scientists are exploring its possible connection to female hormones. They also are studying possible genetic links.

Research suggests that TMD risk factors also might include teeth grinding, which can aggravate the joint, smoking and sleep dysfunction - insomnia or sleep apnea, "anything that disturbs the normal cycle of sleep," Kusiak says - but there is no evidence that "a bite that is off, or constant chewing on one side" causes TMD..."
