I had back surgery in italy 25 years ago, they removed an erniated disc L4-L5 no fusion. I am 45 years old now and since then I had major problems with my back. I have been seeing chiropractors for the last 15 years, three months ago I started to have pain in my lower back down to my leg and ankle. The family doctor prescribed anti inflammatories and pain killer more than a month ago, no help. Did Bio-flex laser therapy (still ongoing) for the last three weeks, no help. Had an MRI few days ago, waiting for the results. Would I be a candidate for an endoscopic surgery if there is no other options?
