Radiating means spreading outward. Radiating pain is pain that starts in one area and spreads until a larger area hurts. Sometimes this is due to the nerves - for example, if a nerve gets pinched or pulled, it may hurt all along the nerve instead of just at the one spot that got hurt. Sometimes it is due to the body's attempt to compensate for the injury - for example, if you hurt your ankle, you may feel pain in the opposite leg as you try to avoid putting weight on that ankle.
