Hello,
Welcome to the ehealthforum and I am really glad to help you out.
TMJ disorder causes pain or tenderness in the face, jaw joint area and clicking, popping, or grating sounds in the jaw joint when opening or closing the mouth. The symptoms that you are having are related to the TMJ disorder.
You can apply warm compresses to the joint and take anti inflammatory pain killer drugs after consulting your doctor. A physical therapist can also be approached as craniosacral therapy to relax the muscles and fascia of the jaw is very helpful in relieving the pain.
as first line of treatment, you should go in for the day and night splints. In addition, biofeedback instrument such as a biofeedback headband also helps at night. Reconstructibe dentistry, arthrocentesis (joint irrigation), surgical repositoning of jaws and oral surgery (as last resort) can also be tried. Surgical method should be tried in end. So firstly go in for splints.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
