Thanks PP. I switched detergent and that didn't help. I did think about the TP issue since the irritation is in only that area and not any other part of my body. I switched TP for a week, but that didn't seem to make a difference. Also, when you have to go out an use TP in other places, how would you manage that? How long would it take to see a difference?
I don't think it's that, if only because it comes and goes. Sometimes it's mild and sometimes it looks like welts. Again, it wouldn't seem like an allergy since it's limited to that part of the body, but maybe I'm wrong about that.
Any other ideas? I do appreciate the input.
