My husband had a lump on his calf for years that he called a hematoma, a year ago, a hole formed on his thigh that oozed out pus, white "starchy" looking pieces and a little blood, on and off. Since then another hole has formed and oozed and a third one is about to break open. It doesn't really hurt him, except when he's squeezing the pus out, and his calf is almost down to its regular size. We believe it's healing, but I'm worried about the holes, one is about 1 cm
