Don't worry... First I would suggest you to consult a doctor and send him pictures in wats app to examine.... Secondly don't take spicy or non veg food for few days... Take normal boil food and take bath with neem boiled water. Don't use soap for few days... Also sleep with some neem leaves spread in your bed... Don't put any ointment or cream in the rashes... Hope you will get well within a week.. God bless you
