Could I do anything to to make a pulled neck muscle go away in about a day or two?

I get those all the time, and some stuff that helps is to put heat on it. What I usually do is take a wet paper towel and put it in a plastic bag in the microwave for about 30 seconds then take it out and just lay on your bed or couch or something until it gets cold. but the main thing that helps is SLEEP. Just sleep a lot and I don't know if it will go away in a day or two but sleep really does help. So if pull it one day then just get more and more sleep each day it will be less painful until finally after aout three or four days its gone, but apply a lot of heat and sleep a lot and maybe it will go away in a day or two.
