I had ACDF surgery July 2011. I did NOT wake up in the hospital with my arm pain gone! Unlike some lucky people. The first month of recovery was hellacious. Lots of pain in my arm and shoulder. It wasn't until the 5th week that the pain began to lessen. It's now four months later, and I'm down to about 1800mg. of Gabapentin daily, instead of 3600 mg. before my surgery. Of course, I hope I continue to improve, but sometimes I wonder why it's taking so long (I had two huge disc herniations as a result of a fall. Have no DDD at all).
