sounds like a form of trigeminal neuralgia

earth clinic is a good site for experiences with natural healing. drugs are not recommended ever. you should look into high dose vitamin B3 and magnesium (glycinate or malate, NOT oxide)
it might be that some people here that have tinnitus might want to have their Dentist look at the around the head Xray during their next visit..
