The clinical manifestations of lumbar pain and leg problems are mainly due to the occurrence of lesions in the lumbar spine, such as lumbar disc herniation, which leads to nucleus pulposus protrusion and compression of nerve roots, resulting in lumbar pain and bending difficulties, and also affects the nerve dystrophy of the lower limbs, resulting in soreness, weakness and numbness of the lower limbs. Patients with osteoporosis of the lumbar spine or legs can also develop this phenomenon due to a large loss of calcium in the bones, resulting in nutritional disorders in the local muscles, and in addition, patients suffering from rheumatoid arthritis and other diseases can have this phenomenon. Therefore, if a patient has back pain or leg problems, the patient can be instructed to reduce activities and rest in bed, and symptomatic treatment can be taken to relieve this phenomenon.
