What is a physiologic effect related to unrelieved pain?

Unrelieved pain has significant negative effects on various physiological processes in the body, and decreased healing is one of the primary consequences. When a person experiences severe or chronic pain, their body's stress response is activated, leading to the release of stress hormones such as cortisol. This response can inhibit the immune system, reduce blood flow to healing tissues, and impede the body’s natural ability to repair itself.

Additionally, pain can lead to increased muscle tension and decreased mobility, further contributing to a slowing of the healing process. In contrast, effective pain management can facilitate better healing by promoting relaxation, enhancing circulation, and improving overall physical and emotional well-being. Understanding the impact of unrelieved pain on healing is crucial in a clinical setting, particularly in the post-anesthesia care unit, where effective pain management directly correlates with recovery outcomes.
