Hi all, I've been on a combination of Gabapentin and Cymbalta for my PN for a few years now. It has worked fairly well up until recently. However, for the past few weeks I been experiencing pain way beyond what I had been accoustomed to. In the past, when pain levels have increased, my neurologist has tinkered with the Gabapentin and Cymbalta dosages until some combination seemed to work. My question is, have any of you become immune to a certain degree from your medications and switched outright to a different treatment? Or is it worth continuing with what worked in the past until the right combination is found? Thanks for any input!
