Chewing gum for days.than jaws/ears pain started same day. ears were infected,pus, on meds.but spasms/tremors happening around top of tmj and by ear?

2 separate issues: Glad your ear infection is being treated. Now your joint issues need evaluation and treatment. Call your a Dentist for a joint examination, and stop insulting the jaw joints...stop chewing gum.

TMJ overuse pain: Your symptoms are consistent with temporomandibular joint pain, likely from temporomandibular joint disorder. Your doctor or dentist can help with diagnosis and treatment if it does not improve on its own.

Stop the Gum!!: Excessive gum chewing seems to aggravate your TMJ. Cease and desist!!
