Has Lyrica Worked For You?

I have been disabled with radiculopathy, degenerative disc disease and severe arthritis. I deal predominantly with severe nerve pain in my legs (from the hip to my toes, front and back of the legs.) Recently I was prescribed Lyrica but I don't seem to be getting any relief from the burning sensation in my legs. Can anyone reflect on whether Lyrica works for nerve pain. And if so did you gain weight?
