Why do people with frequent numbness in their hands and feet often have what diseases?

When we keep the same posture for a long time, due to blood compression and poor blood circulation, we may experience numbness in our hands and feet after suddenly changing posture. This is actually normal. But if the numbness in your hands or feet lasts for a long time, you should pay attention. So what may be the reason for frequent numbness in your hands and feet?

Why do my hands and feet often feel numb?

1. Numbness in hands and feet that does not require treatment: due to incorrect sleeping or sitting postures, which lead to compression of the limbs and insufficient blood supply; or due to cold, which leads to poor blood circulation. In this case, massage after activity or warming up, if necessary, can relieve the pain.

2. Diabetes: Numbness in the hands and feet of diabetic patients is a manifestation of neuropathy. It is mostly caused by high blood sugar leading to autonomic nerve dysfunction, which causes numbness in the limbs of patients, often accompanied by soreness and swelling in the limbs.

3. Hypertension, high blood lipids, thick blood, etc.: Long-term high blood pressure, high blood lipids or thick blood lipids will lead to poor blood circulation, obstructed blood flow, and insufficient blood supply to the limbs, resulting in numbness of hands and feet.

4. Drug-induced: Some drugs or chemical substances, such as berberine and metronidazole, can also cause numbness in the hands and feet. If you stay in an environment containing hydrogen, arsenic, carbon disulfide, etc. for a long time, you may also experience numbness in your hands and feet.

5. Neuritis: Neuritis causes nerve damage and abnormal function, which in turn makes certain parts of the body unresponsive, manifested as numbness and weakness in the hands and feet, muscle atrophy, etc.

6. Nerve stimulation: Numbness caused by nerve stimulation is often localized. For example, cervical spondylosis can cause numbness in the hands and arms, and lumbar shoulder nerve stimulation can cause numbness in the legs.

7. Rheumatism, cold, and joint strain: Abnormal joint function caused by inflammation, trauma, etc. can also cause patients to experience numbness in their hands and feet.

8. Arteriosclerotic disease: It often occurs in middle-aged and elderly people. It indicates worsening arteriosclerosis or is a precursor to cerebrovascular disease, and is often manifested as unilateral limb numbness.

What disease may people with frequent numbness in their hands have?

There are many factors that cause numbness in the hands, among which the following are the most likely to occur:

1. It may be cervical spondylosis. Cervical disc herniation can cause numbness in the distal hand.

2. It may be thoracic outlet syndrome. The tension and pain of the scalene muscles will stimulate the brachial plexus, causing numbness in the upper limbs and hands.

3. The reason for forearm extensor injury is that if the forearm is injured, the nerve will be compressed at the lateral epicondyle of the humerus, causing numbness in the forearm and hand.

4. Pain in the infraspinatus area. The trigger points of the infraspinatus muscle will stimulate the nerves and cause numbness in the hands.

5. Another cause of hand numbness is damage to the ulnar nerve, radial nerve, and median nerve.

What is the problem of frequent numbness in feet?

1. The possibility of lumbar disc herniation, because the herniated disc compresses the corresponding nerves, causing numbness in the feet distal to the nerves.

2. Piriformis and gluteus medius syndrome: due to gluteal muscle strain, the gluteal nerve is compressed, and numbness will also occur at the distal end of the corresponding nerve.

3. The popliteus muscle is damaged, which compresses the tibial nerve and eventually causes numbness of the foot.

4. Damage to the common peroneal nerve can also cause foot drop and numbness of the foot in the corresponding branch.
