YES, I know exactly what you are talking about. I used to get them all the time. It is a form of shingles that come from chicken pox. it involves that particular nerve. that is why it hurts so bad. when it starts at first it feels like a tingling, then a pimple coming then it gets out of hand. a prescription is called famvir. it needs to be taken right away. also theres a cream called zovirax. i also learned that if i feel it coming on i take a vitamin called l-lysine. since i have been taking that the 1st sign i haven't had an outbread for about a year. I would either try the l-lysine(sold at any drug store)right away or go to the dr.and get the famvir. although it best works at the beginning. good luck. i'd like to know if it helps. that sore is a terrrible thing to go through. I know.
