What are usually the first symptoms of compartment syndrome?

The first symptoms of compartment syndrome typically include pain and pressure in the affected area. This condition occurs when there is increased pressure within a muscle compartment, leading to inadequate blood flow and subsequent tissue damage. The pain experienced is often severe and disproportionate to the injury, and it may worsen with passive stretching of the affected muscles. Additionally, the feeling of pressure is due to the swelling and the restricted space within the compartment, which can significantly impair circulation. Recognizing these initial symptoms is crucial for prompt diagnosis and management, as delaying treatment can result in serious complications, including permanent muscle and nerve damage.

Other options such as fever and chills, loss of appetite, or skin rashes are not characteristic of compartment syndrome and do not align with the pathophysiological changes occurring in this condition. These symptoms could indicate other medical issues but are not the primary signs that clinicians look for when diagnosing compartment syndrome.
