HI, I have a small deep-red dry itchy spot, a little larger than the circumfrence of a pencil eraser on the forward facing skin of my scrotum ... I vaguely recall several days ago, while in bed, suddenly jumping out of bed , thinking i was bit by an insect down there because of the sudden stinging pain ... thought a spider or something may have bit me, though I didn't discover one... and now last night I just noticed this deep red spot, though my scrotum has been itchy for a few days now ...
