Burning sensation in the fingers without a clear trigger and without abnormal appearance may be caused by neurological factors, i.e. subjective feelings of patients due to excessive stress in life, mental tension, etc., which can be gradually relieved by proper rest. If it is caused by organic lesions, it may be due to peripheral neuritis, carpal tunnel syndrome, cervical spondylosis and other diseases, which require appropriate treatment measures for the cause: 1. Peripheral neuritis: it is a type of disease in which the sensation and movement of the distal extremities are impaired, and the onset may be related to poisoning and nutritional disorders. When it occurs in the hand, it can cause a burning sensation in the fingers, and sensory loss or motor impairment can also occur. If you have similar symptoms, you should seek medical attention and treat the cause according to the cause of the disease, and take nutritional drugs such as vitamin B1 and vitamin B2. In the daily diet, you can also eat foods rich in vitamin B, such as animal offal, soybeans, egg yolk, etc.; 2. Carpal tunnel syndrome: It is a common clinical nerve entrapment disease, often caused by excessive use of hands. The pathogenesis is related to the increased pressure in the carpal tunnel, which causes the median nerve to be compressed, causing a burning sensation in the thumb, index finger and middle finger, which are innervated by the median nerve. The initial judgment is usually made by flexion test, i.e., flexing the wrist at the maximum angle, and numbness in the thumb, index finger and middle finger can occur within a relatively short period of time. The clinical treatment is often conservative, such as custom-made braces and oral or injectable anti-inflammatory drugs, such as dexamethasone, which can be taken at a professional institution. At the same time, excessive stress on the affected fingers should be avoided in daily life; 3. Cervical spondylosis: It is a disease caused by degenerative lesions of the cervical spine. Since there are nerves traveling inside the cervical spine, in the case of osteophytes and herniated discs, nerve entrapment can occur causing a burning sensation in the fingers, and radiating pain in the upper limbs is also often seen. If the symptoms are mild, conservative treatment such as cervical traction therapy or exercise of the neck muscles can be used. In severe cases, surgical treatment can be taken. In addition, attention should be paid to not lowering the head for a long time or maintaining a fixed posture in life, and the neck can be moved appropriately if conditions allow, so as to relax the neck muscles and relieve the pain.
