Greetings Crayons Welcome to the Skin Problems Healthboard.
I hope the needed comfort is found, have a hug. It is impossible to say with out a dermatologist consult there are so many skin diseases. Rashes can have the possiblility of being contagious so I would not share towels or linens and keep from touching things as much as possible and use frequent hand washing. I would keep the skin, cool, dry, in light and avoid sweets and fats. Peace, sjb
