I have tmj and general anxiety. could either of these cause my chin to tingle?

The answer is yes!: TMJ can wreck havoc with the muscles of your face and chin. General anxiety may cause TMJ. We know that while we sleep our brains are still busy trying to solve problems of the day. TMJ can be a consequence of this hard work. Perhaps your dentist can give you a night guard that can protect your mouth and facial muscles from TMJ.

Not usually.: Not usually. If the chin continues to have tingling, see MD or oral surgeon/

Of course, anxiety: symptoms are not a sign of illness, they are the mind's ability to produce the "flight or fight" response which gives rise to many physiological changes include chin tingling, heart palpitations, nausea, dry mouth, etc. Depending on the cause of your anxiety symptoms, your health care provider can provide you with treatment options. See a dentist for TMJ consultation.
