I was experiencing sciatica for a long time and it was discovered that I had spinal stenosis, disc degeneration, and a synovial cyst. I had a laminectomy and fusion surgery on L4 & L5 two years ago. Even though sciatica did not completely go away, my doc kept saying it was normal. Then it started to worsen about six months ago, so he did a myleogram. It showed spinal stenosis, a bone spur, and disc degeneration in L2 & L3!! He said it was common for the unstableness to keep moving up the spine once you have the rod and pins put in. He has suggested the epidural cortisone shot and I have an appt. next week for a consultation with a pain clinic. In the meantime, the sciatica is SO bad, nothing helps except ice, and laying on my stomach across my physio-ball to decompress. There is NO comfortable position - standing, sitting, walking - all make it worse. I am at my wits' end!
