I was watching The Untold Stories of ER last night and a woman came in complaining about feeling bugs crawling around in her head. Well...of course everyone thought she may be hallucinating because they could not see a thing. Finally, a couple of holes was discoverd in her scalp with fluid bubbleing out of it and sure enough....a black worm poked out of it! The doctor got his tweezers and pulled out 3 black worms from her scalp! The woman remembered that she was in Costa Rica a few months prior and thought maybe some bug layed eggs in her hair and when they hatched, they migrated to her scalp and burrowed in. YUK..YUK..YUK!
