A few weeks ago I was on my couch and my legs got cold. So I put a blanket on my legs. After a few minutes or so from my knees up to almost my hips it felt like heat was coming out of that area. It only lasted a few minutes. When my cold feet seem to feel normal all of a sudden the heat came from them. I thought there was a fire under my blanket and the heat was shooting out. Told the Neuro but he didn't say anything then. I had an lp after and it was normal. So yesterday and now today I'm having the hot spots again! Anyone know what this is?
