I've been taking Lyrica for fibro for several months. It has helped me with the burning nerve pain I had been getting in my arms and legs with any activity. Definately worth trying.
But don't expect it to cure your fibromyalgia. It is designed to deal with just the neurological pain aspect and there are aches that it doesn't seem to touch. Does nothing for the fatigue either, although some people say it makes them more tired. (I'm too tired to notice any slight change. )
Good luck,
Nan
