Thank you for query.Herpes can manifest as tiny water filled swellings(vesicles) which may be grouped many times.They may start with fever malaise .usually they are associated with pain or burning sensation or itching.there may be many cases asymptomatic or without pain.They usually are prone for recurrence.recurrence are less severe and go on decreasing over period of time.It may be due to fungal infection.Please take following precautions.Use loose cotton clothes.Keep area dry.Apply antifungals like clotirimazole.clean the area twice daily with warm water.Treat your partner also to prevent recurrence.consult doctor if does not subside.You can get back to me for any clarifications with the photos.Dr Bharatesh D Basti Dermatologist.
