They have informed me they are not migraines or trigeminal neuralgia. Best guess... atypical facial pain that is on the left side and runs up by temple and scalp. All dental and endodontic stuff looked into as well. Root canal only took away tooth sensitivity. Indocin at 75mg helps on the bad days, but i would rather not take it every 8hrs every day. Lots of risks using that over a long period of time.
