Hello. Thanks for writing to us at healthcaremagic Frequent relapse or recurrence of fungal infection could be because of inadequate treatment or duration of treatment or it could also be due to underlying raised blood sugar. If I was the treating doctor I would have treated you with topical as well as oral antifungals for the required duration of 4-6 weeks (for groin infection). Even though you might notice symptomatic improvement (clinical cure) as early as a few days but unless and until you complete the course and there is mycological cure, you might face a relapse. I would also check for your blood sugar levels. I suggest that you seek another appointment with your dermatologist and get a prescription for both oral as well as topical antifungals. The important part is to take it for the required duration as suggested by your dermatologist Regards
