Hi there, I tried Lamictil and it did ramp the pain down about 2 points. It also made me itchy all over and it felt like my skin was on FIRE. I really wanted to hang on and keep using it because of the pain relief (plus the mood stabilizing was a big plus for me) but my doc took me off it even though I did not have the dreaded Lamictil Rash (which can bring on Stevens-Johnson Syndrome).
I hope it gives you some relief.
The advice I got over and over was to ramp up reeeeeeeallly slowly - much more slowly than the doctor recommends - to avoid any itchy scratchies or rash.
