I have like a hole on my left breast off to the left side about 2 inches from the nipple . It s red and puss comes out of it, and SOMETIMES it sings when i touch it, but I don t want to touch it, but it keeps scabbing over but its very thin layer, so when i even rub against the layer it comes off and starts pussing. A little blood too was on my bra in my sleep. Should i be worried? Im only 17.
