I had surgery on my L4 and L5. I had it fused and screwed. one of the screws was touching a nerve which resulted in nerve pain all down my left leg and foot. they re-operated and the pain went after 6 months after the op. Now, i have got this very unusual sensation down my thigh, i can only lift my leg up slightly before the pain comes whereas my right leg is fine. I am wondering if i could get any advice on this and ways to stop the pain as the pain is unbearable?
