I think I may have got "ring worm" fungus infection on my neck from wearing a used wool coat I purchashed off of EBAY I did notice the coat had several cat hairs on it when I got it? maybe a cat used it for a bed? it also had cat scratches on it, the seller advertised it as brand new never worn. I wore it the same day I got a haircut at the barbershop and the lady did scratch my neck with the straight razor, I think maybe the coat collar rubbed on my neck and some fungus from the coat may have cause the skin infection? or possibly got the infection from the barbershop?
