Thanks for writing to us.
From the description it seems you might be having frictional dermatitis
. It occurs due to occlusive clothing or friction due to clothes in areas which are usually moist due to sweat like groins, axilla
, infra mammary area or in between butt cheeks. Treatment involves avoiding tight clothes. Keeping the area dry and well ventilated. Applying a combination of mild steroid
and antifungal cream. You may also dust the area with antifungal powder to prevent further episodes.
Hope that helps. Take care.
