There are many ways to heal a sore or stiff neck.The fastest is to go to the store and buy a neck brace and wear that at least three hours daily and as you sleep. Other ways are cold and hot pads, neck pillows when you sleep,and avoiding sitting in one spot for long periods of time(computers or gaming systems). On a personal level I know that pain is fixed by the brain.What food is it that feeds the brain the most nutrients?????? FISH FISH FISH....I usually will eat fish for lunch and dinner as i am taking vitamin c to help my immune system.I drink plenty of water to help my muscles calm or hydrate. But the most important thing that you can not do while having a stiff or sore neck is drink alcohol.Alcohol will numb the pain yes,but you twist your neck a lot when you are drunk which wil make it worse.
