Can cervical spondylosis cause leg weakness and fatigue?

Cervical spondylosis may cause leg soreness and weakness, but not all types of cervical spondylosis lead to this symptom. Cervical spondylosis can be classified into different types—cervical type, radiculopathy type, vertebral artery type, sympathetic type, and myelopathy type—depending on the involved tissues and structures. Among these, cervical spondylotic myelopathy may cause leg soreness and weakness. Its main manifestations include numbness and a heavy sensation in one or both lower limbs, followed gradually by difficulty walking, tightness in the leg muscles, slow stepping, and an inability to walk quickly. Therefore, when symptoms such as leg soreness and weakness occur, it is recommended to seek medical attention promptly. A clear diagnosis of the type and severity of cervical spondylosis can be made through examinations and assessments by a qualified physician, and active treatment should be carried out under the doctor's guidance.
