* Take a few days off. Keep the area clean and dry.
* Try diaper rash ointment or maybe Aloe Vera and perhaps something like neosporin or OTC acne ointment.
* Cover affected area(s) with bandaging… such as a hydrocolloid or semiocclusive hydrogel dressing. Personally, I'd use this along with an anti-bacterial ointment. This especially if you aren't taking days off.
The goal is to avoid infection and speed healing. You don't want boils forming.
_For the DIY folks... diaper rash cream is primarily zinc oxide +- an anti-bacterial/anti-fungal ingredient carried in something like petrolatum. Some also include hydrocortisone_ Enjoy.
