I have tmj not in alot of pain no clicking ect, but i get this awful pulsating and tingling and tightness in my jaw, and crawling and itchy feeling in my ear, (same side), what is causing this. my dentist here in the uk says it is a muscle imbalance, got a NSI orthotic to wear at night on my teeth but it is no help, any suggestions whats causing this, oh and my nose tingles to, and sometimes over back of my head.
