Nerve compression syndromes occur when a nerve is pressed or squeezed, leading to pain, numbness, or weakness in the affected area. Common examples include carpal tunnel syndrome, where the median nerve is compressed at the wrist, and sciatica, which involves compression of the sciatic nerve in the lower back. These conditions can result from repetitive movements, injury, or anatomical abnormalities. Symptoms often improve with rest, physical therapy, or changes in activity. In some cases, medical intervention such as surgery may be necessary to relieve the pressure on the nerve. Early diagnosis and treatment are essential to prevent long-term damage.
