Hi Louisa! My AS started in my neck, so I tried everything. The foam pillows didn't work for me either! The best thing (for me) has been massage. Whether I go pay for a real one, try to do it myself, or guilt my hubby into a quick neck rub, it always seems to help the most. When I go to a massage therapist, I always ask for an occiputal release. They kind of pull your head gently away from your body. It's actually quite fabulous! I even bought a little accordian-like contraption called a Pronex that you lie down in and pump up to achieve the same thing. Hope you find something that works for you. I know how rotten neck pain can be!
