Hello, You are suggested not to touch, scratch or pick it. Take care of your hygiene, Be gentle with yourself. Wear soft cotton clothes. You should not use any harsh chemical beauty products rather use herbal products that are gentle for the skin. To prevent itching, apply ointment hydrocortisone on the affected area. It will reduce itching. Take antihistamine at bedtime. This will help to reduce allergic reaction and also help to reduce inflammation, soreness and discomfort. You can take Acetaminophen after food if you have pain. It helps to control spread due to inflammation. The symptoms may be indicative of Jock itch. You can apply ointment clotrimazole on the area affected, it will help to clear the infection. If needed you can take a course of antifungal medicine orally. The infection should get cleared in a week or two. If resistant, get clinically examined by a dermatologist. You may need a course of corticosteroids. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
