I am a 64-year-old male in relative good health. Prior to surgery, I was having severe sciatica in my left leg. My surgery involved: 1) revision left L5-S1 microlumbar discetomy, 2) partial pediculectomy on the left at L5 to free the L5 nerve root (which was severely compressed according to my doctor), and 3) lysis/removal of scar from a previous surgery. After surgery, I felt great. I had some numbness and tingling in my left leg, but very little pain. Within a week, the sciatic pain has returned at a moderate to moderately severe level. Is this uncommon? My concern is because I had so little pain initally, but now the pain has returned. I've followed my post-op instructions well, except still having to strain with my bowel movements, despite increasing my fiber. Maybe I'm not being patient enough, but I can't help having these concerns that something is wrong. Any and all responses are greatly appreciated.
