Since I had back fusion surgery, L4, &L5, titanium rods and screws. Three spacers retro pulsed into my spinal canal. The pain is worse now than before the surgery. I now have to take more medication, and get.steroid shots 2 to 3 times a year. The Laser Spine Institute in Tampa claims they can get rid.of stenosis, and sciatica which both developed after the surgery. The laser Spine Institute would like 10,000 cash even though they accept my insurance. Are you familiar with laser surgery that can cure spinal stenosis and sciatica?
