I am 4 days post-op with a L4-L5 Microdiscectomy and am having trouble sleeping. I've been on my back with pillows under my legs since the surgery, but can't seem to get comfortable that way anymore. I've tried lying on my sides but I'm just not sure that it's healthy to lay that way. Does lying on your side affect the spine alignment? What about lying on your stomach? Are these positions physically unhealthy ways to sleep? I still have some nerve pain and am getting some pain in my hips now, which I assume is all normal and due to edema. I'm just so concerned about allowing this disc to heal so it doesn't herniate again. Any suggestions are appreciated.
