I am currently taking Lyrica 75mg 2 times per day. Unfortunatly I am having side effects.Cognotive function, sleepiness, weight gain, sexual issues, swelling of feet. I had hoped the side efffects would get better with time, because I think I am getting some pain relief. I have tried Nerontin and I does not work for me. I was wondering if Topamax worked for nerve pain not just for migaines. Please let me know if anyone has had releif or if there are an studies on Topamaz and fibro pain.
