I have had a skin infection for over 2 years. it started after I sanded hundred year old barn wood. I've been to the ER several times they gave me antibiotics but it is not cleared it up no one has tested it it seems to have a cycle I'm not sure if it's bacterial, yeast, or fungus. it is on my arms mostly lower my legs slightly face and breast. it is only on the front of me not on the back of me. Please help
