I think I have PN as well. For years I've had spinal stenosis, L5-S1 spondylolisthesis, herniated and bulging discs that no doctor would fix. Now it's too late for me. After THA 1-1/2 years ago anterior approach on a Hana table, my left foot is cold, heavy, the skin feels funny. My walking is slow, stumbling, painful left leg. The surgeon said he could have stretched or compressed the lateral femoral cutaneous nerve that could have caused this problem. I am going to try the physiatrist that was suggested in an earlier post and need to check out the color change in my ankles and lower leg. Doctors are like car salesmen, once you buy it, they're gone. Any suggestions?
