Hi Martina ~ Unfortunately, this happens all too often. Too many people go into surgery hoping for pain relief, and they come out worse than when they went in.
MOST surgeries correct only the mechanical problems - but they don't fix pain problems. Most often, you're left with the same pain or worse. If ANYONE gets pain relief, it's a fluke. They're just plain lucky.
I'm so sorry this has happened to you. I'm in the same shape you are only in the lumbar area. I had TWO lumbar surgeries (open) and I've been disabled since 1995 because of them. I also have permanent sciatica. I'd like to wish the fleas of a thousand camels into the armpits of my surgeon.

The big JERK.
God bless and take care. Hugs, Lee
