I have had the Trigeminal nerve checked in brain after 40 it can be a problem for women and causes jaw pain ,it is not it either. Plus touching the teeth with my tongue makes the pain worse,its hard because there is pain and your tongue goes to where it hurts my family dentist told me.No Dr or dentist can find the answer so they label Chonic pain and put you on drugs.I am an active health 42 year old woman that is living with weird jaw pain for 3 years.
