What can i do about a crick in the neck?

Depends: If by "crick" you mean localized pain, take a Tylenol (acetaminophen) and may be put a warm towel over the site. If you are unable to move your neck, you need to be examined by a doctor. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
