Can tmj cause muscle twitches in your bicep?

Not usually: Common TMJ symptoms include pain/tenderness in the face, jaw, neck and shoulders, and around the ear when you chew, speak, or open your mouth; clicking, popping, or grating sounds in the jaw joint when opening or closing the mouth; difficulty chewing; face swelling. See your physician for evaluation. http://www.nlm.nih.gov/medlineplus/ency/article/001227.htm

Doubtful: Unless you are having some other neurological issues that may include the face and jaw areas, I would doubt that a TMJ/TMD problem can create some bicep twitching.

Unlikely: Unlikely, unless you have associated head, neck and shoulder pain from your TMJ.
