i went to the doctor this week because... i found blood in my pubic area.. so i was like what the hell..and like 5 min later.. i found a blister the about twice the size of a BB filled with fluid.. so i was freaken out.. i thought it was herpes or something.. i went to the doctor and he told me it was nothign to worry about.. it was from growing so fast. so that relieved me... what actually happend about the blood was the same thing that occurs in pregnant women.. he said that one of my stretch marks busted open.. and thats where i was bleeding from.. and the blister was either a heat blister from sweat or something i forgot.. thank god it wasnt herpes... no special treatment.. just told me the usual.. stop working out for a month or so.. and put neosporin on the busted stretch mark.. and for the blister just ride it out.-- just some fyi.. in case someone else gets it.. and starts to freak out.
