Frequently Asked Questions
What is the pain scale?
The Numeric Rating Scale (NRS) rates pain from 0-10, where 0 = no pain and 10 = worst possible pain. Mild: 1-3, Moderate: 4-6, Severe: 7-10. It is the most widely used pain assessment tool in clinical settings.
What is a 'good' pain score?
The goal is not always zero pain, especially for chronic pain. Generally, pain management aims for a level that allows functional activity and sleep. For acute pain, a score of 3 or below is often considered acceptable.
Why is pain assessed using multiple measures?
Pain intensity alone does not capture the full picture. Functional assessment evaluates how pain affects daily life, sleep, mood, and activities. This guides treatment decisions beyond just pain medication.
What is the WHO Pain Ladder?
The WHO Pain Ladder is a stepwise approach: Step 1 (mild pain): non-opioid analgesics (acetaminophen, NSAIDs). Step 2 (moderate): weak opioids + non-opioids. Step 3 (severe): strong opioids + non-opioids. Adjuvants can be added at any step.
