My bedroom looks like a supply room for the pillow department. I've found that not only does one pillow not work for every "issue" but even when I find one I like, it usually only works for a period of time. I am assuming it is because something heals just enough that "things" change...so I just keep trying different combinations.
Some people like the memory foam pillows for their neck/head, and I have used one in the past, like temperpeutic....I've tried one and am not a big fan, but some people seem to swear by them.
Do you have trouble when sitting? If so, have you heard of Back Joy? I've had one for about 4 years now and use it all the time. I used to lug it with me any time I went to a movie, a restaurant, a play, etc...anytime I would be sitting for any period of time.
