Hi all, Im John 37 years old and just had L4-5 spinal fusion. I went through a L4-5 disectomy about 14 months ago and the disc eneded up collapsing. Im wondering how much walking is too much after surgery. I just had the surgery Monday April 9. I still have considerable back pain from the surgery. Its terribly hard to lay on my back, so I have been splitting time between sleeping in bed on my side or sleeping in a chair. The nerve pain I was having seems to be much better so far. I get up and walk every 45-60 minutes unless Im sleeping, which is a lot! I walk through the house about 5 times and also walk down the street about 4 houses and back. The DR claims the only way to get the back pain from soreness and stiffness to go away is to walk and not lay around. How do I know if Im pushing too hard with the walking? Sometimes the muscle pain subsides a bit and next time its back full bore. Guess Im just confused and dont want to mess this surgery up.....but the pain subsiding would be nice too. Thanks for any insight you all have.
