It's very imagined how you're sleeping, or if you have a problem beside your spine in your nouns. Try sleeping with smaller quantity pillows if you use more then one. For me I notice this helped a bit. For me the chiropractor be the only entity that really helped (besides twinge meds). Good luck, it is not fun.
