This is a subject that I've wanted to discuss with others for a very long time. I've had three different responses from three different doctor's. On my lower back where I had all 3 of my surgery's the sking on and around that area stays warm all of the time. As the pain level increases, the sking on my back becomes even hotter. Many times it's been as hot as fire! As least in my opinion. It covers an area of about 8 inches in diameter. Sometimes it can turn a s little pink and occasionally even feel swollen. But the heat of the skin is my biggest concern/wonderment. Does anyone else else have this? In the winter time I can run my hand along my back and the skin will be cold, until I get to that infamous 8 inch circle and then I feel the warmth. And as I said, the heat rises along with the pain. My mom, husband, sister, and doctors have all felt it. If anyone knows why this happens I would really like to know. Also, I would like to know if your's gets hotter when your pain is higher? Here are the 3 things that I've been told. (1) it's inflammation,(2) it's normal, (3) it's an allergic reaction to the hardware in my spine. My surgeon doesn't know about it yet, it's been years since I've even seen him. But I am looking for a new one to go to. (Not that there was anything wrong with him) I just want a set a fresh eyes. OK, who has this and why does it happen?
