Hi. My doctor took me off of my Lyrica since it wasn t doing anything for me anymore for my Fibromyalgia, and he put me, on what he called a grandfather medication to Lyrica, called Gabapentin. I have been on it since about the end of May. All of a sudden, about 3 weeks now, I ve been getting stabbing pains along my left and right sides of my body, slight/minor chest pains, and back spasms? Could this be the Gabapentin doing this to me?
