When I was having neck problems I used a closly knit mans sock, filled it with oat groats (could use rice or cracked wheat also) until it was solid but flexible, stitched up the open end. Put it in the microwave and heat for 3 or 4 minutes until it is hot. Be careful putting it around your neck if it is too hot! It gives a nice moist heat that feels very penetrating. Try it!
