Hi. Greetings. You seem to have a fungal infection AND MUST GET TREATED. Fungal infection is quite common, especially more common in men. This is often related to humidity, tight clothing, excess sweating and accumulation of moisture. You'll need to keep the area dry, wear lose clothing. You'll need to see a dermatologist for confirmation of infection and treatment with oral antifungals and creams. If there's resistance to one particular medicine another medicine may be needed depending on your improvement. DO NOT USE OVER THE COUNTER CREAMS LIKE BETNOVATE GM OR PAN DERM OR QUADRIDERM... this will only prolong the infection. Hope this helps. Caution: Make sure you see a qualified MD / DNB/ DVD dermatologist for all your skin and hair issues. Don’t be lured in by quacks. Know your treating doctor/ discourage quackery! Warm regards, Dr Govind Suresh Mittal. Bengaluru
