I have seen many people who experience frequent neck pain, especially upon waking.  Here is a hidden reason, that very few people know about: mercury.  Many times people will have sushi or fish for dinner and wake up with a crick in their neck.  Why? Because the mercury from the fish has attached to their spinal cord or nerve.  I have found this to be the case time and time again with Nutritional Analysis.  My suggestion for people who eat fish often, and also experience awakening with neck pain, is to have charcoal tablets on hand when they eat fish, to neutralize the incoming mercury, and have it safely pass out of their body.  Mercury toxicity is also a common cause of chronic pain in other parts of the body.
