If there is numbness in the fingertips of the hand, if the numbness of the fingertips is only a sensory disorder such as numbness, there are many problems of sensory disturbance. In that case, peripheral neuropathy (peripheral neuritis), etc. is suspected, so it becomes a region of neurology (rarely, it may become a range of orthopedic surgery when nerve compression at the spine level). Peripheral vascular circulatory dysfunction is suspected if there is a feeling that blood sometimes does not pass. It is characterized by symptoms such as the fingertips of the hand becoming white even when viewed from the outside (circulation returns again after a few minutes).
If the symptoms of peripheral vascular circulatory failure appear to recur, Raynaud's disease (due to various causes such as smokers, autonomic dysfunction and stress) is suspected. In addition, as a cause of numbness of the fingertip of the hand, there are a wide variety of diseases causing peripheral vascular circulatory failure such as collagen disease, neurological disease, blood disease, endocrine disease, vascular disorder, orthopedic range, and neurological disease. If you experience numbness in your fingertips, first, consult your doctor.

. Numbness of the toes

Many nerves are connected from the waist to the feet, but the nerves may be damaged for some reason and the toes of the toes may be numb. The cause of numbness in the toes of the foot is also numbness due to fatigue from the waist. The following are examples of diseases and disorders related to numbness of the toes.

・ Diabetic neuropathy
Diabetic neuropathy is a complication of diabetes. When diabetes occurs, peripheral nerves weaken, causing numbness in the hands and feet, numbness in the toes, and pain. If the blood glucose level continues to be high, the nerves in the hands and feet will be damaged. Although there are numbness and pain in the toes of the toes, there is not much decline in muscle strength. If you treat diabetes while the symptoms are mild, your neuropathy will recover. When the symptoms worsen, the tissues such as the feet become necrotic, and in the worst case, there is a risk that the feet must be cut.

・ Lumbar disc herniation

In addition to low back pain, a lumbar disc herniation may cause numbness from foot to toe. A disease in which the intervertebral disc protrudes and stimulates nerves to cause pain. Symptoms are pain from the lower back to the feet, mainly back pain. Numbness of the outside of the foot, the sole of the foot, and the toes. When it gets worse, it ca n’t stand. It may improve naturally, but surgery is indicated when numbness or pain in the foot worsens

Numbness on the face

Numbness in the hands If facial numbness causes symptoms such as facial numbness, pain in the ears, difficulty in closing the eyes, whistling, hypersensitivity, or spilling from the mouth during eating The possibility is suspected. Causes of facial palsy can be caused by trauma or underlying illness causing numbness or numbness of the face, and the idiopathic manifestation of numbness or numbness of the face alone, although there is no specific cause There are cases. Moreover, it can be divided into the case where there is some lesion in the brain or the brain stem which is the central nerve, and the case where there is a disorder in the peripheral nerve coming out there. Among them, the symptoms and course of Bell's palsy, which is peripheral facial nerve palsy, is characterized by sudden numbness or paralysis of the left or right face of the face. Prodromal symptoms may cause pain behind the ears on the side where facial numbness or paralysis occurs, but most often suddenly develop weakness on one side of the face without any signs, and motor paralysis appears.

Numbness in the hands

The cause of numbness in the hand is thought to be because the nerve is compressed in any part of the neural circuit from the hand to the head (brain). Nerves pass from the head through the neck bone, under the clavicle, and to the arms, elbows, wrists, and fingertips. The cause of numbness in the hand is that any part is being compressed, but there are several parts that are easily compressed. ■ Around the neck bone ... Deformation cervical spondylosis and cervical disc herniation may cause cervical bone deformation and cartilage to protrude, causing nerve compression and causing numbness of the hand.

■ Under the clavicle: When the nerve under the clavicle is pressed, it is a disease that causes numbness of the hand called thoracic outlet syndrome. It is easy to happen to a shoulder woman.

■ Inside the elbow: When the nerve inside the elbow is pressed, it is called elbow canal syndrome. Symptoms such as numbness in the hand (particularly numbness in the little finger), pain, muscle atrophy, and weakness appear.

■ Wrist ligament: Carpal tunnel syndrome occurs when nerves in the wrist ligament are compressed. Symptoms caused by bruises and excessive use of hands by computer. In addition, it is a disease that causes numbness, which is said to occur easily when the balance of female hormones changes before and after childbirth and menopause. In addition to the above, the causes of numbness in the hands are central diseases such as cerebral infarction and brain tumors. Symptoms such as numbness of the hand, the feeling of tongue tangling, and feeling of uncontrollable rotation may be central numbness, in which case it is necessary to consult a neurology department. Even with cerebral infarction, if patients can be diagnosed in a mild manner, symptoms such as numbness may be improved by taking medicine without being hospitalized. In contrast, hand numbness is often caused by stiff shoulders and fatigue of the arm, not a serious illness. Even, in any case, early detection and treatment of the causes and symptoms of hand numbness are important.
