It is nice when one gets to opine on a history that is so well detailed. Your problem does seem to be of a 'fungal' nature. I could be wrong but my clinical hunch is a dermatophytosis
or a fungal infection
. For best results, do visit your dermatologist
on the ground next to you or upload a clear photograph using the 'upload data' icon on this page or use our premium ask-a-doctor feature. As for the treatment, start with the application of a corticosteroid-antifungal combination cream applied locally twice/day & then switch in 3-5 days to a pure antifungal cream eg 2% ketoconazole
applied similarly for 2 weeks. If an oral antifungal
is desireable, please visit your doctor for a prescription. Cheers & wish you good health!
