Many of us need a water bed or air mattress. Finding the right pillow can be a challenge. Due to neck TrPs, many of us have hardly any curvature in our neck. The standard cervical pillow doesn't work. It is a trial and error procedure to find out what worked best.
Some people prefer a small pillow that is soft enough to mold the way they want it.
Some use a water pillow. Sometimes, when we find out what works well, our body changes, and we must begin the search again. Infections and infestations can run down your body and reduce its ability to recover. Remember that your immune system may be down due to sleep deprivation, or hyperactive due to neurotransmitters. Previous surgeries and previous physical traumas can create adhesions and weak areas which are targets for TrP formation.
