Hi Christy,
This with info on pillows might be of interest.
A friend in work was telling me some time ago that her brother went to all sorts of back experts over a period of a year and eventually found that the whole problem was down to the pillows that he was using so your theory could well be right.
This advice taken from might help:
[SIZE=-1][SIZE=-1]Choose the right pillow[/SIZE][/SIZE]
[SIZE=-1]Your pillow cradles your head all night, working with your mattress to keep your neck and body properly aligned. If you're always adjusting your pillow or if you wake up with a stiff neck, it might be time to check if you're using the right kind of pillow.[/SIZE]
[FONT=arial,helvetica,sans-serif][SIZE=-1]Experts say that side sleepers generally need higher and firmer pillows than back sleepers. If you're a side sleeper, make sure your pillow won't compress much when you're sleeping. Most polyester fills will flatten noticeably in a few months, but synthetic and latex foams stay springy for years. If you sleep on your stomach, try a down pillow that you can squash flat. If that isn't comfortable, you might be better off without a pillow. Also, if you wake up with a headache or sniffles, try switching materials. You may be allergic to down feathers or sensitive to synthetics.[/SIZE][/FONT]
