Pain is a complex and subjective experience that encompasses both physiological and psychological components. It is generally defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Understanding pain is paramount in the nursing context, as it informs effective pain management strategies that prioritize patient comfort while ensuring safety. Pain can be classified into various types, with acute and chronic pain being the most commonly recognized categories. Acute pain is typically short-lived and often results from injury, surgery, or illness. It serves a crucial biological function by alerting the body to potential harm. In contrast, chronic pain persists for an extended period, often lasting beyond the expected time for healing, and can lead to significant emotional distress and functional impairment.
