Nerve Entrapment Syndromes

Nerve entrapment syndrome occurs when a nerve is compressed or pinched by surrounding structures, leading to pain, tingling, numbness, or weakness. Common types include carpal tunnel syndrome (median nerve), cubital tunnel syndrome (ulnar nerve), and tarsal tunnel syndrome. The compression can result from repetitive motion, injury, or anatomical variations.
