The document defines pain from both a clinical and patient perspective. It discusses theories of pain transmission and categorizes types of pain as either acute or chronic, and by location and cause. It also covers factors that influence individual pain perception and lists common pharmacological and non-pharmacological pain management approaches. Assessment of a patient's pain involves determining details about location, characteristics, aggravating/alleviating factors, timing, severity, and perceived cause using the "WHAT/WHEN/WHERE" mnemonic.
