My boyfriend has a quarter sized bump half way down his inner thigh. It s hard feel like a nod it s almost has a purple/ dark hint to it. Almost looks like a spider bite nod but no puncture spots. He cut it open a little and squeezed it like a pimp and blood comes out some dark and thick some red and in between it seemed like it went down a little it didn t go away. He did it again a few days later same thing? What could this be? I told him he should go to the doctor.
