Chronic compartment syndrome (CCS) occurs when pressure builds up within the body’s muscle compartments. Compartments are made of sheets of connective tissue called fascia. These sheets are under the skin of the arms and legs. They wrap around groups of muscles, nerves, and blood vessels. When pressure builds up in the compartments, it disrupts or blocks blood flow to the muscles and nerves.

Unlike acute compartment syndrome, CCS is not an emergency. However, you should see your doctor to get treatment.
