I have difficulty swallowing, a trembling jaw and pressure under my ears while eating. i have a history of anxiety. should i be concerned?

When it comes to: symptoms in a person with anxiety - medical causes still need to be ruled out before it can be assumed that the cause is anxiety.

TMJ?: Sounds like a TMJ problem. Make sure anxiety controlled. See TMJ expert for opinion about jaw symptoms. 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.
