Spine lumbar fusion surgery. Anyone else?

I am almost 3 weeks post op from spinal fusion L3 L4 and L5. I am walking 45 minutes daily. No more pain down the back of my legs. But definitely pain from nerves healing etc. I was so afraid of this surgery but after 5 years of dealing with it I was finally ready. I still have a long way to go but , I thought I would write in this forum because I used to scan it prior to surgery. I’m willing to answer any questions. I had surgery done by Rothman in Philadelphia
