Welcome to HCM,
Recurrent fungal infection
can occur due to poor immunity.
You should get your blood sugar(PP), T & DLC checked checked.
You can take tablet Fluconazole-150 and apply Surfaz-SN/Quadriderm ointment twice daily locally after morning bath and before going to bed.
You should wear loose lingerie made up of cotton and keep the area dry and ventilated.
Deodorants reduces it by reducing secretion of sweat only.
