I have severe pain in the front of my left leg to the point of using a cane to walk. I had three injections first to SI joint, second and third to L4-L5 and Si. I get about 2-3 weeks of relief before I am back in pain. I take Gabapentin, Arthroteck and tremadol. I can't afford 371.00 after insurance every 2-3 weeks yet I can't live with this pain.
