Pain is a symptom: Pain is a symptom that tells a person something is probably damaging some part of her body. It's just a symptom. Thousands of conditions can cause pain, in various parts of the body. "Horrible pain" usually means it's horribly important to have a doctor's evaluation right away before something horrible finishes happening. An ambulance ride to the ER may be needed, depending on one's circumstances.
