I do not have a diagnosis of fibro, but I have chronic Lyme disease and myofascial pain syndrome, so I have a lot of symptom overlap. I find that
neurontin is helpful in covering up some of the neuropathic
pain associated with my illnesses. It will do nothing for muscle pain, just like how NSAIDs (like Advil) will do nothing for nerve pain.
Also, as my doctor described it to me, it can take awhile to hit the right dosage with neurontin.
