I suspected it from using boxers at bedtime which were unwashed for a week or two until some itch occurred and rashes developed on my thighs, lower extremities even at my
face and arms. Due to some forceful scratching, some cuts developed on my groin. Sometimes, fluid gets out from it leaving some brownish discolorations on my undies.I've already used antibacterials (tab or topical) but it didn't make it better.
