neuropathic pain
"I experienced severe back pain for more than 5 years with some relief with Naproxen and chiropractic care.  I finally retired because I could no longer cope with the pain.  After going to a Sport and Spine practice they finally diagnosed me with subcostal and intercostal nerve pain in my right rib cage and put me on gabapentin; 300mg 2 times day.  Within about 5 days the pain was gone.  It does make me tired and I've gained a couple of pounds after being on it a month, but the benefits outweigh the side effects.  It's been a miracle drug for me after suffering so long."
