What is the relationship between numbness in hands and feet and cerebral infarction? What diseases are numbness in hands and feet a precursor to?

Numbness of hands and feet is an independent disease caused by damage to the motor nerves of the limbs. It is mostly caused by cervical spondylosis, lumbar spondylosis, rheumatism, cardiovascular and cerebrovascular diseases, hypertension, diabetes, etc. So what is the relationship between numbness of hands and feet and cerebral infarction?

1. Numbness in one hand may indicate cervical spondylosis

If numbness occurs on one side of the arm or fingers, it may be caused by cervical spondylosis, which is usually a chronic, recurring numbness accompanied by symptoms such as soreness and stiffness in the neck and shoulders. The disease is easily caused by working with the head down for a long time, exposing the neck to cold, or using a pillow that is too high.

2. Numbness in the upper limbs and legs may indicate lumbar spondylosis

Numbness of hands and feet caused by lumbar spondylosis is numbness of the upper limbs and legs caused by lumbar vertebral lesions. This scattered numbness of the limbs occurs when local nerves are stimulated, such as lumbar spondylosis, lumbar disc herniation, etc. Intervertebral disc compression of nerves can cause difficulty in movement and even incontinence. This falls under the category of lumbar spondylosis. Depending on the situation, you need to see a lumbar specialist, take a CT or MRI, and have an expert confirm the diagnosis and then develop a treatment plan.

3. Finger numbness or weakness may be carpal tunnel syndrome

Carpal tunnel syndrome refers to a disease characterized by thickening of the transverse carpal ligament, swelling of the tendons within the tunnel, tissue degeneration caused by congestion, or degeneration and hyperplasia of the carpal bones due to wrist trauma, fracture, dislocation, sprain or strain, which compresses the median nerve and causes numbness and weakness in the fingers.

4. Unilateral limb numbness may be a precursor to cerebral infarction

If numbness in the hands and feet occurs on one side while the other side is completely normal, you should be alert that it may be a precursor to cerebral infarction. Limb numbness caused by cerebral infarction is usually acute and may be accompanied by symptoms such as speech disorders and hemi-limb movement disorders, so in this case, you must seek emergency medical attention.

5. Symmetrical numbness should prevent diabetic lesions

Peripheral neuropathy caused by diabetes often presents with symmetrical pain and paresthesia, with symptoms in the lower limbs being more common than in the upper limbs. Sensory abnormalities include numbness, crawling ants, fever, and electric shock-like sensations, which often spread from the distal toes to above the knees. Patients have sensory abnormalities like wearing socks and gloves.

6. If you have persistent numbness and pain, beware of tumors

If elderly people experience long-term chronic numbness in their hands and feet that persists and does not improve, it may be caused by a malignant tumor. In the late stage of the tumor, the distant site effect will produce corresponding neurological symptoms, such as numbness and weakness in the hands and feet, and unsteady walking. Therefore, if the common causes are not found, a comprehensive examination must be conducted, such as the liver, stomach, blood, etc. Women need to pay special attention to the ovaries and breasts. So as to detect tumors as early as possible and treat them in time.
