Sore and sleepy legs may be sore muscles after prolonged standing, sitting or walking long distances or strenuous exercise; in addition, it may also be a lumbar disease, such as lumbar spinal stenosis or lumbar disc herniation leading to sore and sleepy legs; there are also vascular causes, such as poor blood supply after arteriosclerosis, resulting in soreness and sleepiness due to insufficient blood supply to the legs, which requires attention to timely examination. If it is only muscle pain caused after straining, standing or sitting for a long time, you can choose to massage and soak in hot water, and at the same time you can take painkillers, such as Fenbendazole, etc., which can improve significantly after 3-5 days of treatment. If the pain does not improve, consider that it is caused by lumbar disease, you can improve the magnetic resonance examination of the lumbar spine to accurately determine the condition. If the cause is considered to be vascular, you can improve the vascular ultrasound examination of the lower extremities to help determine the cause.
