Legs feel warm when on each other as well as the popliteal space but when assessed using the hand it neither feels warm or hot. heat's from the inside?

Hmmm...: That just means one's hands feel cooler than one's legs, which could be due to the legs being warmer than the hands, or the legs being perceived in the brain as being warmer than the hands... but none of this has any meaning UNLESS there are unusual symptoms other than the legs seeming warmer. Unusual symptoms might be leg rashes, leg pains or swellling, bluish or pale hands, etc...
