hi thanks for writing here...If you have sweating and itching in your genital areas then it is high chances that you are be suffering from fungal infection
.It usually occurs here since area is very moist.Try to keep area as dry as possible.Start applying antifungal dusting powder,use loose and cotton clothings,do not apply any cream over it since it may moist and worsen the condition.You have to take oral antifungal
drugs ,you can take tab.terbinafine
250 mg daily at night for 3 weeks along with anti allergy tablet like cetrizine
. ,i hope this will cure your problem.Take care.
