The problems you are having sound a lot like mine except I did have surgery. If I had to do over I would have tried some of the procedures mentioned first. It may have given me relief without surgery. Since my surgeries in which my L1 was compressed with spinal stenosis and degenerative arthritis I have had the ablation which didn't work, nerve blocks. They feel the pain I am having again in my leg is from a pinched nerve. Six weeks ago I had a spinal stimulator implanted. It is finally starting to give me relief but I still had groin and buttock pain so I just had an injection in my iliac joint (I think that's what it is called). It is the most relief I have had in over a year. I can stand without pain. I know it is only temporary but it is wonderful. The final decision is yours. Just don't go in like I did with very little knowledge. Read, discuss with others and get a second opinion. Best of luck to you.
