My name is Candy, and I started having facial pain last September 2009. Had a root canal that was supposed to cure it, but of course, that didn't work. I began 400mg/day of carbamepazine in February and some days later, my heart rate was averaging 80-100bpm - too high - so my neurologist prescribed Baclofen instead. Will start the replacement tonight. Will let you know how it works. I am hoping for the best, as I am very active and need to have my life back.
