Red bump on stomach, pus filled, painful. Is it a pimple?
My boyfriend noticed a red bump on his stomach just below his belly button. It is red and looks like a pimple , but it is enlarged to the size of a nickel. He thinks it s a sweat bump, but it is very painful. We poked it and some puss came out and now when he squeezes it, a clear liquid comes out. What is this and what can we do to make it less painful and hopefully go away?
