Scabies will not go away on it's own. There is an over-the-counter medication that you have to slather all over your whole body (and all members of the household). You also have to clean EVERYTHING in your home - towels, sheets, blankets, carpets, etc.
This all has to be done at the same time because the scabies can live on and off of your body, so if you slather yourself in medicine without cleaning your blankets and towels, they will not go away (and visa versa).
Good Luck, I know it's not fun!
