Symptoms
If you're experiencing a medical symptom, such as pain or
fever, it can be hard to think of anything else. Symptoms are usually a result of your immune system's natural defenses against irritants and
disease, but some symptoms can be a sign of a serious medical condition. Check the Symptom Dictionary on HowStuffWorks to learn what your symptoms mean and how to manage them.

Sunburn results when the amount of exposure to the sun or other ultraviolet light source exceeds the ability of the body's protective pigment, melanin, to protect the skin.
