Lyrica is used for nerve related pain. You don't need to be diagnosed with Fibromyalgia - that's just what the manufacturer is advertisting right now as targeted marketing becuase there have been no meds that address Fibro. But, like I said, it can also be used for nerve pain. I tried Neurontin first and then Lyrica. While both relieved the nerve symtpoms pretty well they both made me very dizzy. I have heard of some people who use them and it works well. If I hadn't had the dizziness I would have continued using one or the other.
