Summary
This study looks at how headaches work by using capsaicin (the spicy part of chili peppers) and ice water to trigger mild, temporary pain in people with and without headache disorders. Researchers measure changes in pain signals and tear production to better understand conditions like migraine and cluster headache. The goal is to find better ways to diagnose and treat these painful conditions.
