More common are:

Because of cold, fatigue, standing for a long time and walking for a long distance, the muscles and soft tissues of the lower limbs are strained. In this case, the patient can be advised to rest properly, raise the affected limb, give massage to relax locally, and usually combine physical therapy with hot compress to get satisfactory relief.

In addition, patients with degenerative diseases of cervical or lumbar spine, such as cervical spondylosis, lumbar spinal stenosis, lumbar disc herniation, etc., can also lead to nerve compression symptoms such as numbness and weakness of lower limbs. For this kind of patients, it is suggested to go to a regular hospital in time, improve relevant auxiliary examinations, make clear the degeneration of cervical or lumbar vertebrae and nerve compression, and give timely and correct treatment.

Old people feel weak when walking, which may be due to malnutrition, calcium deficiency and osteoporosis, or it may be due to the compression of sciatic nerve by lumbar degenerative diseases. Secondly, if there are cerebrovascular diseases, such as insufficient blood supply to the brain, stroke, cerebral infarction, cerebral hemorrhage, etc., these symptoms may also appear. We should go to the hospital as soon as possible for systematic examination so as to take targeted treatment measures.

The reason for this may be: 1, the physical function of the elderly is reduced and muscle strength is weakened. Therefore, there is a situation in which the legs are soft when walking. 2, the elderly leg muscle weakness caused by osteoporosis, leg weakness when walking. 3, caused by brain diseases in the elderly, such as cerebral infarction or cerebral hemorrhage. 4, lumbar disc herniation, lumbar spinal stenosis, etc. Therefore, we should go to the hospital in time, make clear the cause and have targeted treatment.
