Hi, I have been suffering with back and sciatic pain on and off for the past few years with symptoms changing every few months.Cause L5/S1 disc protrusion. I have been scheduled for a microdiscetomy on the 11Nov13. I have had over 5 facet joint and epidural injections over the past 12 months with different degrees of short term to long term relief. My last injection was 4 weeks ago with another great result. My concern is i am currently in no pain at all but my disc is still large and my surgeon still wants to operate. My symptoms before my last injection consisted of chronic right buttocks, hamstring and calf pain only when standing in one spot for long periods of time or kneeling. several months ago I could barely walk 100m before I had to sit down the pain was so intense.The pain was so bad I had to lay down and that still did not give me instant relief. I am confused as to what I should do. I feel as though at the moment I could run a marathon with no pain. However, I am schedule to have a microdisctomy in a month. I wish my pain was back because if it was I would feel more confident going into my surgery. Should I go into an operation feeling great even if its the cortisone is only providing a temp fix. Open to all suggestions and advice.
