Hello and welcome to healthcaremagic
I would keep a possibility of
fungal infection. This is because closely opposing body folds e.g thighs and groin, axilla, submammary folds etc can trap sweat, heat and moisture, therefore making the area favorable for fungal proliferation.
If I was the treating doctor I would have asked you to use a
topical antifungal like clotrimazole/sertaconazole/luliconazole cream, twice daily, regularly for 4 weeks. Etaze AF cream contains topical terbinafine+
mometasone. I would rather prefer a plain antifungal like clotrimazole/sertaconazole/luliconazole because mometasone if used for too long can cause side effects like skin atrophy and striae
Since you are already using an
Oral antifungal e.g oral terbinafine once daily. I would suggest you to continue with it for 4-6 weeks for a more complete cure
An OTC antihistamine e.g
cetrizine 10mg once daily would help you in symptomatic itch relief.
Keeping the folds dry by using an antifungal dusting powder would help in preventing the recurrence.
