Empty legs can be caused by overwork, osteoporosis, lumbar spine disease, lower extremity vascular disease and other factors.
1. Overwork: Walking too much or doing strenuous sports can lead to overwork of leg muscles and other soft tissues, impeded local blood circulation and excessive accumulation of lactic acid, resulting in leg soreness and fatigue and other discomforts.
2. Osteoporosis: Age factor and postmenopausal women can have osteoporosis, which can lead to bone loss, destruction of bone trabeculae, and changes in bone microstructure, which can cause leg weakness and pain.
3. Lumbar spine diseases: Lumbar spine diseases such as lumbar disc herniation and lumbar spinal stenosis can cause nerve compression, resulting in numbness, pain and other discomforts in the innervated areas of the legs.
4. Lower extremity vascular diseases: Lower extremity arterial embolism, arteriosclerosis occlusive disease, varicose veins and other diseases can cause obstruction of blood circulation in the lower extremities, resulting in insufficient blood supply locally, which in turn causes the emergence of discomfort in the legs.
When the legs are empty, you should consult a doctor in time, under the guidance of a specialist to actively carry out appropriate treatment, which will help to alleviate the symptoms of discomfort as soon as possible.
