Just had this procedure done (3 weeks ago) for my L3,4 &5. Almost 11years ago to the day, I had similar surgery for S4/5. Three weeks into recovery mode and pretty much pain free. Soreness and minor back ache (mostly around the incision area) are still there but improves daily. The sciatic pain, which prior to the surgery was pushing an 11 or 12 on a scale of 1-10, is gone. Occasionally there's a "shadow" pain, briefly, as the once irritated nerves Heal and recover, but even that gets better daily. Muscle relaxer and Tylenol has been all I've used. PM me if you want to get into more detail. Glad to help.
