question: Hello doctor,I am a 33 year old male. After returning from a recent trip to a water park, I have noticed few black spots on my hips. These black spots are itchy, and also slightly painful. There are four to five such spots on my right hip, and one to two on the left side. I applied "Ring Guard" for three days, but the problem has not resolved much. There is also heavy dryness in the area. I am sending you all the relevant pics. Please, can you check the pictures, and let me know what has happened, and how can I treat it?
