This lump appeared on my tummy in a stretch mark a few days ago and now has a dark line in it that looks like blood. Not sure what it is or why it’s started to bruise as I e tried to leave it alone.
Is this a spider bite or something? I’m from Australia. It started out as just a pimple and now looks like this and i accidentally shaved over it and some puss came out. Otherwise I’ll go to a doctor if need be
