What causes numbness in hands and feet?

Some symptoms that cause numbness in the hands and feet are also relatively common. The numbness in the hands and feet is mainly caused by toothache in the upper limb nerves. It is mainly some numbness and pain. At the same time, the nerves are compressed at the elbow and the median nerve is compressed. The most common symptom affecting daily life is cervical spondylosis, which is a disease that is common among middle-aged and elderly people. In addition to numbness in the fingers, cervical spondylosis also has some abnormal sensations.

Other types of symptoms include muscle soreness, some radiating pain and movement disorders, so the common methods of checking cervical spondylosis in daily life are mainly some people who push and pull each other or numbness. They must be treated in time for another common disease such as numbness of one hand.

1. Upper limb nerve compression: (1) It is numbness and pain in the thumb, index and middle fingers, often with a history of waking up from the numbness at night, which improves after waking up and moving around. In severe cases, there may be atrophy of the hand muscles, which affects the fine movements of the hand. This is because the median nerve is compressed in the wrist, which is the so-called "carpal tunnel syndrome". (2) There is numbness and pain in the ring and little fingers, and there may also be a history of waking up from numbness at night. In severe cases, there is muscle atrophy and decreased flexion strength of the ring and little fingers, which affects fine movements. This is because the nerve becomes pinched at the elbow, a condition known as "cubital tunnel syndrome." 2. Cervical spondylosis: The most common disease causing numbness in hands is cervical spondylosis, which is one of the common diseases among middle-aged and elderly people. In addition to numbness and abnormal sensation in the fingers, cervical spondylosis is also accompanied by other symptoms, such as: muscle soreness in the neck and shoulders, radiating pain in the upper limbs or movement disorders. It is not difficult to diagnose cervical spondylosis, all you need is an X-ray. There is also a simple method to check cervical spondylosis. One person supports the affected side of the head and holds the affected upper limb with one hand, abducting it 90°, and pushes and pulls in opposite directions with both hands at the same time. Those who experience radiating pain or numbness can be preliminarily diagnosed with cervical spondylosis. 3 Stroke: Another common disease that causes numbness in the hands is stroke. If symptoms such as headache, dizziness, heavy head and light feet, numbness of limbs, and swelling of tongue often occur, and the patient also has diseases such as high blood pressure, high blood lipids, diabetes, cerebral arteriosclerosis, etc., more attention should be paid and be alert to the occurrence of stroke.

The above is what causes numbness in the hands and feet. Mainly, stroke will cause headaches, dizziness, and some symptoms of high blood pressure and high blood lipids. In addition to numbness in the fingers, cervical spondylosis also has some abnormal sensations. Other types of symptoms such as muscle soreness, some radiating pain and movement disorders must be treated in a timely manner, and they also have a very critical impact on other aspects.
