Good day! Few days ago I shaved my private parts when this lump appeared. It's small at first but after few days it gets larger, about the size of pea perhaps. It is painful when I walk, sit, even when I'm lying to sleep. Last time I checked I can see some sort of black stuff at the top of this lump, not the whole lump per se but just the top of it, some portion of it to be clear. I'm still single, not engaged in any sexual intercouse though I masturbate if that helps. I must be clear that this lump is not located in me testicle, rather at the top of my right testicle, directly underneath the scrotum. Can you guys help me? It's starting to get me worried, and it pains a lot. Thanks.
