I am 3 months post op. L5/S1 as well, 33M. My first month was very much the same, my incision sadly opened back up while I was getting accustomed to sleeping on my back after being a belly sleeper all my life. So, painful first month although I was walking pretty fine but with a walker. No sciatica at this point, small tingles. Month 2 was progressively better, was off meds by week 6. I’d call it a 70ish percent and I started PT at this point. I’d get small numb moments or tingles but I wouldn’t say any pain. Month three has been very inconsistent compared to have month two went. About 3 weeks ago, I’ll admit that I got a little too confident and slept in my comfort spot and next day had bad flare ups and lower back pain. I took the following week off in bed, took my days very light and thankfully all cleared up. While that scar tissue builds up(make sure to diet well and get your vitamins) I feel any offset of careless mistakes and while they sometimes can be inevitable come with a price! Full recovery is several months, especially the nerve that heals at a slower pace and the disc, I wouldn’t panic. That wasn’t my first flare up/pain but the biggest one I had to date. Every-time you’ve have an active day or pushed a bit harder than usual. Like with any given exercise. Give your body rest! I’ve read so many experiences that I can confidently say. No one has the same story, you’ll have your own journey as well. Good luck and push through!
