Acute pain

Acute pain is an unpleasant sensory and emotional experience of sudden onset and limited duration that typically arises as a physiologic response to noxious chemical, thermal, or mechanical stimuli While acute pain serves a protective biological function to prevent further tissue damage, its persistence is expected to resolve as underlying tissue healing occurs

Acute pain is an unpleasant sensory and emotional experience of sudden onset and limited duration that typically arises as a physiologic response to noxious chemical, thermal, or mechanical stimuli It can affect individuals of any age and originate across diverse organ systems, most frequently involving musculoskeletal, cutaneous, or visceral structures following traumatic injury, surgical intervention, or acute medical illnesses Pathophysiologically, it is initiated by peripheral nociceptor act...

Pathophysiologically, it is initiated by peripheral nociceptor activation, transduced via myelinated A-delta and unmyelinated C nerve fibers through the spinal cord to higher cortical centers, and is commonly accompanied by neuroendocrine and sympathetic nervous system responses such as tachycardia, hypertension, diaphoresis, and localized muscle spasm While acute pain serves a protective biological function to prevent further tissue damage, its persistence is expected to resolve as underlying t...
