I was put on Gabapentin for fibromyalgia and was later diagnosed also with peripheral neuropathy. I had serious swelling of feet, toes, ankle and leg with terrific pain. Was then diagnosed with lymphedema. I was referred to a neurologist who immediately took me off gabapentin because it can contribute to the swelling. She prescribed Topamax and I have been taking that for almost 2 months. I would like to note that the swelling and fluid retention did not in any way decrease when I stopped the gabapentin. However, I stay on the topamax because it does not cause weight gain and in fact I have lost some weight. Another plus I see is that I do not have that the feeling of bugs crawling and jerking around in my legs. I am sleeping fairly well. I don't know if anyone else has been prescribed Topamax , but so far I am not having any problems that I am aware of.
