I have an oblong shaped hard lump, maybe the size of a pea, under the skin in my groin area. No color to it, but it did have a flat red spot in the center like a pimple had popped. When squeezed, I got a lot of blood (some stringy blood as well) and a small amount of other matter that looked more like fatty tissue than pus. I put some alcohol and triple antibiotic cream on it, but 24 hours later, it is the same.
