Hi guys, So last night I was in the shower and I noticed a weird spot on my chest. Its like a large blood blister or bloody pimple. In fact I would think it would be a large pimple if it wasnt purple with blood and so large. Also I dont get pimples very often at all. I looked up pictures of melanomas on the net and it kind of looks like them, kind of not. Its about 7mm in width and previously there was no mole there. Doesnt hurt unless I press on it, like a blind pimple. Should I get it checked out?
