I had a laminectomy:discectomy on L4-5. I was in a lot of pain after. Six months after I needed a fusion as it left my spine unstable and my nerves were crushed I was told at a second opinion. I would never go through such a serious surgery on the spine without proper pain meds. I would get a 2nd opinion. I am basically bed ridden now. I was warned not to get surgery and I didn't listen because I had so much pain and faith. Try if you can PRP or massages. Walking and water therapy can help. You will not want to do this at all without proper pain meds.
