@kilikina I hope the out patient surgery helps. It sounds like to me you are having stenosis (your nerves are being impinged) I had the same problem, my pain started at my buttock down to my foot. Had surgery on June 9th. It was a fusion and took 9 hours to fix. I had degeneration which caused a scoliosis, but the main problem was my L-4 & 5 nerves were impinged. The surgeon had to clear out what was impinding (sp) He had to start at T-10 to my pelvis. It was a big surgery. I am now recovering and walking. Can''t bend, twist or lift any thing heavy. My husband has to do a lot that I did, but can't do now. Had to give up my healthy 14 year old dog to where we boarded her. They wanted her and love her. I miss her very much, but can not take care of her.
I did every thing to try and help, PT, exercise,gentle yoga, and a swim class. Nothing helped but more pain and epidurals.
I'm not a doctor so you need to see a surgeon that has experience in this problem. My surgeon had many qualifications. I had my surgery done at Mayo hospital at Rochester, MN. I don't know where you live, but does sound like you are getting help, I hope it will take your pain away. Forgot, my bones are soft so I have to be careful so I don't pull out a screw or rod. I am on Tymlos and injection with a very small needle into my stomach to increase my bone mass. You are lucky to be on pain medicine, so many can't get any pain meds.
