About a few months ago I noticed a hard lump that was noticeable by touch below the skin of my pubic hair, above the penis. I left it alone because it didn't hurt and cause discomfort but today it started bleeding and something like a mixture of blood and water followed. Today a lot of blood came out and it is noticeably swollen red through sight and soft to the touch, and pain is experienced only if a large amount of pressure is applied directly on it. Should I be worried and seek medical assistance, or is home treatment good enough to curb the swelling?
