I had the same problem as you a few years ago. I thought it was a dental problem, visited my Dentist on several occasions in agony, but all was well with my teeth and gums. I was eventually referred to a specialist at hospital, I had several appointments and was given a mouth guard in case I was grinding my teeth. Believe me when I say that made my pain a lot worse! Then on my next appointment the guy checking my mouth asked a colleague to have a look, it turned out that the nerve in my right cheek was so tense it was that that had been causing my pain! The solution he suggested was Botox!!!! I was stunned by that, a few weeks later ( after much thought) I decided to give it a try. I won't go into to the details of how it was administered, as may put you or anyone else off, I can honestly say I made the right choice and it did the job for me!!!!
