Thanks for posting your querry on HCM
I understood your problem.
Ring worms are contagious superficial skin diseases caused by dermaophytes, a group of fungus, who love to reside in warm and moist area and spread by contact with contact with animate or inanimate objects.
First of all get your diagnosis of a dermatophyte infection
confirmed in a lab where there is a mycology set up.
If it is actually a recurrent infection, you can start with a antifungal powder preparation instead of an ointment.
Also you have to take care of the following points:
Wear loose cotton underwear and change it more than once a day
Keep the infected area dry
wash your clothes in boiling water
Try all these steps before shifting to oral antifungals.
Do get back to us if you have still having residual problems at any point of time.
