Hi Doctor, Ive had jock itch for about two weeks now, and Ive tried several things like creams and anti-dandruff shampoo. I read online that castor oil might help, so Ive been applying it before bed and washing it off in the morning. One day, I applied it after my bath and forgot to do it before bed. The oil dried up, and I noticed some black skin, which seemed dead, so I gently rubbed it off with my fingers. The rash seems smaller now. Does this mean that castor oil is just slow in showing results, or could it be something else?

Try using an antifungal cream like Lotrimin Ultra twice a day on the affected area to help clear up the infection faster. Remember to keep the area clean and dry to prevent further irritation.
