So this doesnt sound like herpes? Water seems to make the reddness burn or sting more its so irritating.. I have eczema on my hands but i didnt know i could get it in my groin
Did this outbreak appear around the same time as trying any new lotions, shampoos, conditioners, soaps, laundry products, etc?
Sounds like it's dermatitis caused by sensitivity/allergy to something.
Could also be heat related, friction related, etc.
Try to give the area plenty of air. Wear a housecoat when at home...no underwear.
Avoid soap in the area, and try not to wash the area too much. Water can make skin irritations much worse.
It's possible that you are allergic or sensitive to the medications as well...this could be why they don't work or make things worse.
