Compression syndromes occur when nerves, blood vessels, or other structures are compressed, leading to pain, numbness, or weakness. Common examples include carpal tunnel syndrome, where the median nerve is compressed in the wrist, and thoracic outlet syndrome, which affects the nerves and blood vessels between the neck and shoulder. These syndromes can result from various factors, including repetitive movements, injury, or anatomical abnormalities. Treatment often involves rest, physical therapy, or in some cases, surgery to relieve the pressure and restore normal function. Early diagnosis is crucial for effective management and recovery.
