Some people claim they can get relief from sharp neck pain by drinking a large glass of ice-cold water. Researchers plan to enlist several people who suffer from sharp neck pain in a test. When a participant experiences a sharp neck pain, he or she will take a pill that may be a standard pain reliever or a placebo. Half of each group will also drink ice-cold water whereas the other half will drink regular water. Each participant, equally likely to get either treatment, will then report the level of pain relief they experience.
