Hi, I have really bad back pain, going on for almost 4 years. I had 3 pilonidal cyst surgeries done almost or more then 4 years ago.I even asked the surgeon, if they hit a nerve, he said no we don t have anything to do with that.I had Xray and Mri done a year ago, all came negative.As I type, I have lower back pain, and pain in my left foot, going down to my feet.Please help
