I also highly recommend going to a neuro. If the pain is caused by nerves you owe it to yourself to see an expert...that doesn't mean every neuro is great either..believe me. Throughout the last year or so I was pretty much a guinea pig trying all sorts of meds and mixtures... I am not positive but I do believe I was once on both Trileptol and Tegretol... they are a similar drug with similar effects so I don't believe mixing them is dangerous..but perhaps its kinda overdoing the same type of drug. I had negative results with both drugs so I'm probably not much help, I'd definitely ask your doc to go back to the drug that works best for your pain.
