People with chronic and/or acute neck pain are often overwhelmed with web pages, ads, emails, etc. about what is the best pillow for them. Most bedding stores have a line of pillows they tout as the best pillow to buy for neck pain. Is there any scientific support for the claims made for better sleep, lowered neck pain, and headache relief? Which of the many different designs of support pillow is most likely to be helpful for most people? Are there any risks or problems associated with the use of cervical pillows?
