The correct answer is B: Compartment syndrome.
Compartment syndrome is a painful condition that usually develops over a few hours after a serious injury to an arm or leg that causes pressure within the muscles builds to dangerous levels.
This increased pressure can decrease blood flow, preventing nourishment and oxygen from reaching nerve and muscle cells.
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
Acute compartment syndrome is a medical emergency that without treatment can lead to permanent muscle damage.
