Hello, I have been moving over the last 2 weeks and developed a heat rash in my inguinal area. I m all Iittle on the large side and have had this issue before. Usually I avoid a lot of walking outdoors for a couple of days and it goes away. This time I couldn t rest because I had to keep packing. I may have overdone it, to the point of some bleeding and a small not has formed under the skin, I have been using a diaper rash ointment with 40% zinc oxide, which helps with the stinging, but my wife is worried so here I am.
