I am 81 yrs. old, never had rashes in my life. recently I started a rash around my waist below my naval and on my back side about the same height. I cannot think of any thing different that i'm doing except I made some hot hot chow chow recently and eat a good bit of it at a time. also I did buy a pair of new jeans and wore w/out washing, I do know better, but needed them at the time. any suggestions.
