R52.0: Acute pain

Acute pain is a type of pain that typically lasts for a short time and often occurs suddenly as a result of an injury, surgery, inflammation, or infection. Unlike chronic pain, which can persist for months and even years, acute pain tends to resolve as the underlying cause of the pain heals. This type of pain can vary in severity, from mild and momentary discomfort to severe and lasting distress. It serves as an alert system, signaling the body that immediate attention and care might be needed. Acute pain can affect any part of the body and can cause physical changes such as increased heart rate or blood pressure, sweating, or dilated pupils. Though acute pain generally improves with time, adequately managing this pain while the body heals is important for the person's comfort and well-being.
