Can anyone help with this question? I had a laminectomy 6 months ago and have continued with nerve pain down the right leg (where injury was) and now in the left leg (no injury here). I've had 2 steroid injections with no success. They did a sympathetic nerve block on Wed and I feel somewhat better. Does this mean it is RSD? I don't have the temp change or color change in my extremities but I am somewhat sensitive. Thanks so much.
