I had the burning pain in my neck and shoulders ever since cervical spine surgery in 2007 which kicked my fibro in full gear. I take a narcotic pain med for the overall pain but it never did anything for the burning pain. I tried Lyrica and it didn't work. I had been on Cymbalta for some time and it never helped this pain. A few months ago I began seeing a pain mgmt specialist who put me on Keppra and within two days the burning pain was gone. I have been so grateful. I'm not sure about side effects with it being used off label for pain
