Thanks for your query.
You have a excessive sweating
and itching in groin and near scrotum
.This is due to a fungal infection
the prime cause being your underwear.Pl wash your innerwears in hot water to which a antiseptic son like Dettol
should be added and soaked for 1 hour.Apply(Miccanazole) Daktarin or Zole ointment over affected area after bath.It will subside in 3-4 days.
