My husband has a red swollen knot  on his calf. His legs swell up when he wears socks and the knot started out weeks ago as a lump but flesh colored.Then it started getting bigger and started turning red.It is now about three inches across and is red with a darker color in the center and the skin is starting to peel back on it and it hurts to touch.
