Went to my second opinion on Thursday. The doctor said there was nothing wrong with my spine and that there wasn't a bulging disc at L5-S1. He said that my leg pain was caused by a chemical that the degenrating disc is releasing. He put me on Lyrica. Which I swear has made me gain weight because my clothes are fitting tighter. I have only taken it for 5 days and it seems like I am in a fog all day long. It really makes me sleepy and I am on the lowest dose. Has anyone heard of this chemical being released when the disc is degnerating? Also why would one doctor say there was a problem but the other one said everything is ok? I am still having severe leg and but pain. Something has to be causing it.
