For many patients, changing to a better pillow is a critical key to a healthy and comfortable cervical spine, a solution to chronic neck pain & tension, and relief for headaches.
I have personally experienced this. After five whiplash injuries in my youth, I found that regaining full and reasonably comfortably functioning involved using the right pillow.
What is the “right” pillow?
Our pillow should give us consistent, resistive support during sleep. A down pillow will not provide this because, no matter how carefully you shape & place it when you first lie down on it, it will deform during the night.
Likewise, a memory foam pillow, which indents when you lie on it, does not give consistent support---its softness is appealing, but it is not serving the health of your cervical spine.
The “right” pillow supports the normal curve of your neck, whether you lie on your back or your sides to sleep. It allows your head & cervical spine to remain in alignment with the rest of your spine, not bent up or down.
The pillow that I sleep on, and that I recommend for my patients, provides this, and patients can get this pillow in my office.
