Pain is a complex sensory and emotional experience that occurs when specialized nerve endings called nociceptors are activated by potentially damaging stimuli such as physical injury, heat, or chemicals. The purpose of pain is to alert us to potential or actual tissue damage, allowing us to take action to protect ourselves and promote healing.
