There's no cure for the cold so there's nothing else to really do other than give it time as in a week or 10 days.
You can use a vaporizer though to help add moisture to the air to help your breathe better. Vicks vapor rub is also good to help with colds too.
Rub some vicks vapor rub on your chest and it will help clear up stuffy noses and help if your chest is congested.
