The symptoms of prolonged numbness in the legs are mostly caused by nerve compression in the legs. Prolonged nerve compression will cause loss of innervation of leg muscles, fascia and ligaments, and in the later stage, there will be muscle wasting atrophy, as well as adhesion and contracture of fascia and ligaments, which will lead to weakness of leg muscles, limp and unstable walking, as well as obvious stiffness of the joints and limitation of activities, which will seriously affect the normal function of the patient’s legs in load bearing, flexion and extension, and seriously affect the patient’s quality of life. The quality of life of patients is seriously affected. Therefore, after the emergence of numbness in the legs, it is necessary to consult a doctor in time for examination and treatment, so as not to affect the patient’s normal life in the later stage.
