Hi, I have developed a lump on my groin 2 inches up from my penis over the past few days. It was quite red and sore, and seems to be getting abit bigger. It also hurts when I go to the toilet, as there may be a lump close to my anus, which bleeds when I wipe my bottom. I have over the past 3/4 yrs had a lump on the back of my left shoulder, about the size of a 1p, which doesn't hurt and is quite solid. I have noticed another beginning to form on my other shoulder and with the other lump am starting to become alittle concerned. What could it be?
