Since December my boyfriend has been dealing with constant infections in random places. (Finger, lip, nose, pelvis, legs..) Now I have one. It started as a tiny black dot now its a large hard bump that hurts A LOT. It throbs like a bad burn and I can barely walk with it. It's about the size of a tennis ball under the skin. It won't pop and its getting bigger and bigger under the skin. I don't think its a bug bite either,I haven't seem any insects around yet.. It's still below freezing where I live. Here are some pictures I took.
