Hello, Thank you for your query. This sounds like a fungal infection. I recommend using Clotrimazole cream twice daily for 2 weeks or till the lesion disappears, which ever is later. Then, reduce to once at night for a week and your once every alternate day for a week. Stop the medicine this way. Clean & dry area before applying the cream. Use mild soap. Apply ice covered in a cloth, if it itches Air out the area as much as possible. Avoid constrictive clothing over the area. If the lesion doesn t show improvement in a week, please consult your physician to check for other skin conditions. Hope this helps Please let me know if there is anything else I can help you with. Wish you good health
