Suggest Treatment For Boils & Skin Rash

hello, I have been getting boils for the last 5 months. I had an alergy to mold and had to go to ER doctor said it was from mold. He gave me a fungus cream for rash and I applied it to the healing boils and have not got another one since. I did a mold test in house and within 10 minutes mold grew on test kit. Is is a fact that the mold in or under house can be causing the boiles due to staff?
