Baclofen
"I have severe back pain, and nerve impingement. I have tried at least 7 medications that are used to treat this disorder. There are some that work better but the side effects make it impossible to live a normal life. There are those that don't work at all. This is the only medication that I have taken that allows me to live a normal life. I can sit in a chair or ride in a car without my back spasms killing me. Baclofen is the only medicine I have found that allows me to work without spasms, and not be so fatigued like a zombie. "
