Are TMJ headaches the same as migraines? I've had both, and they weren't really similar in any way. The biteguard by the way only made the TMJ worse for me, and I "cured" my agony - I stopped playing the flute. My jaw muscles were ruined during surgery to take out 4 wisdom teeth, and since we couldn't fix the muscles, I had to stop doing the thing that caused the most pain. It was a difficult choice to quit playing an instrument I loved, but I did, and haven't had any TMJ pain since.
