I feel tingles, some weakness & pain in right arm;pain in neck &some headaches;weight loss & plugged ear.could it be brain tumor? i've tmj and anxiety

Pain in arm or neck: Not likely to get pain in the arm or neck from a brain tumor without having signs of brain stem dysfunction. There are other conditions that need to be considered. Chiari malformation can produce tingling in neck and shoulders with headaches. You might have a couple of unrelated problems producing a confusing clinical picture. (separate neck and ear problem). A good examination might be in order.

Tingles: i would see a neurologist to get a full evaluation. There are many possible causes for the problem

Unlikely: Unlikely brain tumor. But get neurology evaluation to make sure. TMJ can mimic many problems. Make sure your TMJ is being managed by TMJ expert. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask your MD, your dentist and your dental society for referrals.
