Hi. Greetings. Ring worm infection if treated completely and properly usually doesn't recur often or doesn't persist . however if there are factors like increased body weight, excess sweating, or diabetes, the infection may persist or recur. So discuss a proper treatment schedule with your dermatologist near you or you could visit me if you are from Bangalore. Do not use creams like itch guard and pan derm, they worsen infection. Hope this helps. Warm regards.
