My 13 yr old son had a tiny what we thought scratch on his neck behind his ear.It kept bleedin alot for such a tiny scratch.Almost overnight it grew to this very large protuding mole looking mass.He says it's completely painless.It is like a round flesh like dome that oozes blood.The GP said its an infection growing outward and gave him Amoxicillin.6 days into the meds it is still bright red, large and oozing.We put warm water rags on it.Anticeptic solution and keep it very clean and bandgaded all but at night.It looks like a large bloody mole to me.what the heck can this be?
