What term is used for pain that radiates down the buttocks and the back of the leg?

The term used for pain that radiates down the buttocks and the back of the leg is known as sciatica. This condition is typically caused by irritation or compression of the sciatic nerve, which runs from the lower back through the hips and buttocks and down each leg. Symptoms of sciatica can include sharp pain, burning sensations, numbness, or weakness in the affected leg.

Osteoarthritis refers to a type of joint disease that results from the breakdown of joint cartilage and underlying bone, primarily affecting weight-bearing joints. Adhesive capsulitis, commonly known as frozen shoulder, involves stiffness and pain in the shoulder joint. Arthritis is a general term for inflammation of the joint, which can manifest in various ways but does not specifically indicate radiating pain down the leg. Thus, sciatica is the most accurate term to describe the specific symptom of pain radiating from the buttocks down the leg.
