On May 3 I had a lumbar fusion L5-S1. I feel great working 1/2 days and start PT on Wednesday. My problem is I am having a problem with either my sciatica or mt sacroiliac. It hurts so bad that I can't walk very long or do much at all. If I didn't have that pain, I would be doing great, Has this happened to anyone else after surgery? And if so, what did you do to relieve the pain? I am going to call the doctor tomorrow. Just wanted other people input.
