My left leg is weak and limp, what's going on?

Weakness in the left leg is an extremely abnormal phenomenon, which is usually caused by other diseases in the body. Specifically, if the leg weakness and tenderness occur acutely, it is a sign of cardiovascular disease. If the weakness is accompanied by leg pain, it is caused by lumbar spinal stenosis. If you feel like you are walking on cotton when the disease occurs, it is a cervical spinal cord disease. If your legs become weak and your limbs become clumsy and stiff, it may be a symptom of Parkinson's disease.

Acute attack: cerebrovascular disease

For lower limb weakness, the first thing to consider is whether it is unilateral or bilateral. If it is sudden unilateral limb weakness and is not accompanied by pain, cerebrovascular disease should be ruled out, because cerebrovascular disease may cause hemiplegia. In addition, weakness in both lower limbs may also indicate cerebrovascular disease. If you have cerebral infarction, cerebral hemorrhage, etc., you must diagnose and treat it in time.

With back and leg pain: Lumbar spinal stenosis

Some elderly people experience weakness in their lower limbs and pain in their waist and legs, so they need to consider problems with their lumbar spine. Low back and leg diseases are a common disease among the elderly, and they usually feel weak after walking for a while. Lumbar spondylosis may also be caused by gradual protrusion and compression of nerves, accompanied by limb numbness and eventually pain. It is recommended to go to the hospital for a check-up first and then do appropriate exercise. Do not do massage easily to avoid aggravating lumbar injury.

Feeling of walking on cotton: cervical spinal cord disease

Some elderly people feel weak in their lower limbs, and walking feels like walking on cotton, with one foot deep and one step shallow. If you sit or stand for a long time, you will feel overwhelmed and as if you may collapse at any time. At this time, you should pay attention to whether it is a problem with the cervical spine and go to the hospital for a Hoffman sign examination. If your legs suddenly become unable to move and you have difficulty urinating, you should consider sudden spinal cord disease. Vertebral compression and damage to the spinal cord can cause motor nerve disorders. If not treated in time, it can lead to paralysis.

Clumsiness and stiffness: Parkinson's disease

Another type is slow movement. Patients also say that they have no strength to walk, but in fact they cannot take a step. This is due to the stiffness, increased muscle tension and inflexible walking caused by Parkinson's disease. Usually, you feel like you can't take a step and you don't have the energy when you start an activity, but as you walk a little bit you will start taking steps faster. Parkinson's patients feel clumsy and stiff when walking, and are prone to falling when going out. Family members must take good care of them to prevent them from falling.
