I have chronic back pain and have been prescribed gabapentin 600mg 3x a day. Side effects some ankle leg swelling and sweating. Two neuros have suggested surgery at different places in my back L 1 and 2 for a fractured disk and L 3 and 4 for bulging disks. Oneof these neuros says he wants to try gabapentin first. Does it alleviate back pain and will I be able to drive and take care of myself again? Thank you
