Acute compartment syndrome usually develops over a few hours after a serious injury to an arm or leg. Some symptoms of acute compartment syndrome include:
A new and persistent deep ache in an arm or leg
Pain that seems greater than expected for the severity of the injury
Numbness, pins-and-needles, or electricity-like pain in the limb
Swelling, tightness and bruising
A tense, distended abdomen
Wincing when the abdomen is pressed
Urine output that slows down or stops
Low blood pressure
