Alright so about 5 months ago i noticed a small misquito bite-esque lump on my thigh about 3.5 inches directly above my kneecap. After a month, it had not gone away but gotten slightly larger. Still thinking it was nothing, i ignored it. About a month and a half ago, i noticed the lump looked rather bruised and significantly larger, sorta like the size of the flat end of a bic pen. I accidentally cut it shaving, and since then the lump has gotten really painful, bleeds a LOT now with little effort (otherwise known as when i rub my pants against it, it bleeds), and the skin has gotten red and thick feeling around it. What's up with this? Any ideas?
