Hi there elaine. Yes your diagnosis seems to be spot on...dermatophyosis or commonly known as "jock itch". I note you have confided in your husband & as such, STD's may be safely ruled out. However, treatment when taken should target both partners' in close contact & treatment of the fomites (towels/underwear/sheets et al). Please take a single oral dose of fluconazole
200mg (husband may pop one too if all his systems are a go..ie he does not have any liver, heart,kidney
condition); topical application of nizoral
cream) twice/daily for 1-2 weeks; use a 2% ketoconazole soap for the private parts..groin & axillae twice/week with 10 mts contact time for best results & as a preventive measure. Make sure to wash all undergarment sin hot water, sun them well (dont wear damp underwear) & iron out the creases! Trust this will suffice. Agreed it does not appear serious & wish you both good health!
