I have migraine. does it have anything to do with tmj?

Many types : There are several different classifications of headaches and migraines based upon location, severity and symptoms. I would see your dr. Asap to run some tests to hopefully narrow down the type and how to treat. Treatment may entail other professionals too, including a tmj/tmd specialist.

Comorbidity: TMD is an associated factor, but not a trigger or cause for migraine. It is essential not to confuse the issue and suggest a cause and effect relationship because both are present and need separate treatment.

Yes and no: Migraines are "vascular headaches" Headaches associated with TMJ are usually of the "musclular contraction" variety. Many patients call all bad headaches "migraine". TMJ not related with true migraine headaches. See a TMJ specialist to sort out. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists.

Possibly indirectly: Does TMJ have causal relationship w. Migraine? Not directly. Hypermobility Syndrome (HS) sufferers commonly have both. HS begets functional scoliosis & pelvic girdle instability in some; leading to chronic shoulder asymmetry & tilted head; begetting crossed muscle syndromes in Sup. trapezium (ST) & Masseters. I have seen association of chronic unilateral ST hypertrophy/spasm & "chronic migraine".
