A friend has skin lessions. e thought it was spider bites. Upon scratching he pulls out hair like wiggly fibers like microscopic worms or something. He s staying with an alcoholic that can t make it to the bathroom and many times he has to clean up after him. He also pees in his room and on the bed if he can t make it to the bathroom and my friend cleans that up too. It s a pigsty if u ask me. His sores are on his arms and fingers and stomach. He s freaking out cause I look up and scanned online hurried back to the apartment and he s heading to the emergency room. What could it be and I read many of those skin infections are contiagous.
