What's wrong with my feet being numb and weak

I believe many people have experienced numbness in the feet. It is mainly caused by maintaining a fixed posture for a long time, which causes compression on local blood vessels and poor blood flow. Foot numbness can be divided into two causes: physiological factors and pathological reasons. The latter in particular needs special attention. Some serious diseases also have similar characteristics. So, what causes numbness and weakness in the feet? Let’s take a look below.

Irregular foot numbness may be caused by the following diseases:

Osteoarthritis

Osteoarthritis is characterized by local degeneration of articular cartilage and bone spurs on the edges of joints. It can cause damage or insufficient supply to the nerves around the joints, leading to numbness in the hands and feet. It often occurs in the morning and is manifested by stiff and painful joints, friction or "clicking" sounds during movement, and swollen and painful joints when pressed.

Lumbar disc herniation

People with lumbar disc herniation are prone to foot numbness, accompanied by back pain and leg pain, sometimes numbness in the left foot and sometimes numbness in the right foot. This is because when suffering from lumbar disc herniation, the sciatic nerve that controls the lower limbs is compressed. Patients with long-term numbness in the feet and back pain mostly suffer from central lumbar disc herniation.

diabetes

When blood sugar rises, it will cause a series of metabolic disorders in nerve fibers, leading to peripheral neuropathy, which may cause numbness and pain in the extremities, often manifested as numbness in the feet and pain in the lower limbs. If you have a family history of diabetes or obesity, you should consider this possibility if you have long-term numbness in the feet.

Signs of a stroke

For patients with three highs, arteriosclerosis, cardiovascular diseases and other diseases, numbness in the feet may be a precursor to stroke. It often manifests as weakness and numbness of one or both sides of the limbs, accompanied by hearing loss, slurred speech, black spots in front of the eyes, etc., which is medically known as a "mini-stroke." A mini-stroke may precede a full-blown stroke, so be sure to pay special attention to these symptoms.

If the numbness in the feet is temporary due to squatting for a long time or incorrect posture, you can try to separate the big toe from the limbs, stretch the big toe upward, or stretch the entire row of toes upward, and then stomp your feet hard, which can quickly relieve the numbness in the feet. If accompanied by calf numbness, pinch the calf muscles with your hands and stomp your feet hard.
