I did not take Topamax long 'cause it is unpleasant. I took it off-label for an unrelated issue and it cured my Pudenal issue. The neurologist would be the one to ask. Tell them you just want to try it for a bit. After I got relief, my Physical Therapist mentioned that she had read that this helps. What have you got to lose except a week or 2 of feeling a bit off from anti-seizure med? I was 14-1/2 years of treating with everything imaginable. Give it a shot! Makes sense, the nerves are in a spasm.
