Hello I had gone through your question and I really appreciate your concern Here I would like to know about your age and relevant medical history like diabetes or other metabolic disease, any recent exposure to unprotected sex? If possible upload a photograph In my opinion you should wash it properly with antiseptic soap or solution and keep it clean and moist. You should apply anti bacterial ointment like mupirocin or soframycin to prevent superadded infection Please write back to me with these details so that I will be able to tell you more accurately. Best wishes
