When I was having severe jaw pain
radiating to the ear and whole side of my face, both of these worked for
was the same as TN, in fact, they were having trouble edeciding if it was TMJ, TMD, or TN. It turned out to be an internal derangment of the temporal-mandibular disc. Cause by arthritis, the disc has shifted out of place. I didn't even know the jaw had a disc, LOL.
I hope this helps you some, I know how painful it can be. Maybe from too many loud fireworks?
