I had the epidural done as well and unfortunately it didn't work for me. I have had to go up one procedure radio frequency abalation AKA rhizotomy. I don't recommend the procedure and should only be done as a last resort before surgery. It is very painful to have done and the recovery time is long. I had it done almost 6 weeks ago and my muscles are still unhappy with the procedure (I had the nerves burned from L3 to L5). My left leg gets fatigued and painful if I push to hard.
So I hope you have better long term luck with epidurals than I did. I too started out great but after the third one, which lasted a week, I had to go for the RFA...esh!
