9/2012 l held a heavy child on my left hip and felt pain shortly after. It was a l4 l5 herniated disc with sciatica down left leg. Pain was unbearable, but continued to work. I received physical therapy, chiropractic and finally two cortisone injections (which finally helped the extreme pain). 21/2 years later, I am experiencing numbness down my left leg all the way to a knot in the arch of my foot. I received a cortisone shot, but it didn t help much. Now I am told a microdiscectomy will be a good approach? I am also showing a slight lumbar scoliosis in xrays. Will the surgery help after all this time?
