I am 4 weeks after having an ALIF procedure at L5/S1. Immediately after the surgery, my only pain was at the surgical site and due to my bowels waking up. I was able to do several laps in the hallways with a walker while in the hospital for 3 days. Once at home, I was able to leave the walker behind after a couple days and 2 weeks out, I was able to walk for 3 30 minute sessions per day with no pain. Then suddenly I had considerable leg pain that the doctor said was normal rebound pain from the nerves waking up (he prescribed Gabapenten which relieved the pain). I then started getting pain in the back around the surgical site that the doctor said was muscle pain (he prescribed Cyclobenzaprene which has had little to no effect). He also mentioned using a heating pad which has had some effect in reducing the pain. At 4 weeks I can barely walk for 5 minutes without the pain becoming so intense that I need to sit. I have been very careful in my movements and always use my corsette. After progressing so well in the first 2 weeks it is discouraging to be in so much pain at 4 weeks. Has anyone else had a similar experience? Is this a normal progression for an ALIF procedure such that I can expect steady improvement from here?
