Hi Thank you for asking HCM I have gone through your query. Your problem with penis can be most likely due to fungal infection. In such case i would recommend using ointments with combination of antifungal like miconazole and cortcosteroid like flucinolone. Avoid using soaps and irritants to wash the area and instead you can use saline or warm water. Get enough exercise daily, drink lot of plain water,take fresh fruits and vegetables. These all will ease constipation. Using medicated shampoos with ketoconazole at least twice weekly will help in getting rid off dandruff. You can use over the counter ketoconazole shampoos like nizoral or widely available ones like head & shoulders or selsun shapoo. Hope this may help you. Let me know if anything not clear. Thanks.
