Chronic Migraine Worsens Jaw Pain
Frequent migraine headaches increase the risk for another painful condition – temporomandibular disorder, or TMD – according to a recent study. TMD causes jaw pain and clicking and can result in difficulty chewing.
Researchers from the University of São Paulo's Ribeirão Preto School of Medicine in Brazil conducted the study and the results were published in the Journal of Manipulative and Physiological Therapeutics. According to the researchers, people who experience migraine attacks on 15 or more days of the month are three times more likely to have severe symptoms of TMD. Previous studies suggested a link between migraine and TMD, but this is the first to examine migraine frequency and jaw pain severity.
The study involved 84 women in their early to mid-thirties. Twenty-one of the study participants had chronic migraines, 32 had episodic migraines, and 32 women with no history of migraine were included as controls. TMD symptoms were observed by researchers in 54 percent of the women with no history of migraine, 80 of those with episodic migraine, and 100 percent of women with chronic migraine.
