had discectomy , decompression L4/L5 7 years ago, the operation was a success in terms of the problem with severe sciatica through my right hip and leg,I have have still got lower back problems and constant spasms in my right leg.using anti iflam & amitriplyn tabs at night relaxes the muscle spasms at night.The advise I would give is use the gym on a regular basis , non impact exersice, and plenty of core routine , strenghen your abbs and lower back , also swimming, keep yourself active, but at all times protect your problem with respect , everything in moderation, it works for me , good luck
