Feel a bit of numbness, tingling under ear but next to the jaw. also a little discomfort.not tmj because my jaw does not lock, but what could this be?

Numbness, tingling: Your jaw does not need to lock to have TMJ. TMJ dysfunction can manifest as jaw pain, ear pain, headaches and migraines, numbness and tingling, etc. Your symtoms could also be related to wisdom teeth, teeth or gum infection, or ear problems. You should have this examined by a dentist and/or and ENT specialist.

Hard to say: Not enough information. If it troubles you, see either a TMJ specialist or ENT doc.

TMJ and Anxiety: There's a link between depression and anxiety symptoms and TMJ disorder. See orofacial pain specialist and CBT psychologist near you for evaluation and treatment.

Could be TMJ: You could be having a TMJ problem even thought your jaw is not locking. In addition to a medical evaluation, I would suggest that you see your dentist to have your TMJ evaluated.

Probably TMJ: Jaw locking is but one of the symptoms of a dysfunctional TMJ. But may also be fractured tooth, fractured jaw, infected throat, infected ear, or one of a myriad of other problems. Please don't try to self diagnose. See a Pro, see your Dentist.
