I tried Lyrica for the burning pain that I get in my arm and I could not take it long enough to even see if it would work. My feet and ankles kept swelling up so I had to stop it. I tried neurontin and really liked it but I was also worried about weight gain as I am already overweight but I also had the brain fog with it and it seemed to get worse the more I took. Tried Topamax and no relief so now I am taking Gabitril. I am seeing some good results so far. I still have twinges of sharp pain or burning but it is reduced. I am starting another dose in the morning on the weekend. I like to wait till the weekend in case I can't drive while on it. So I hope that you find something that will work for you...Sue
