Diseases always sneak up on people when they are not expecting it, seemingly without warning, but in fact they are always revealed to us inadvertently, only that we do not pay attention to them. If your finger pain, even if it is mild, is related to the pathology of the body, it should be taken seriously and needs to be examined in the hospital to find out the cause as early as possible and treat it as soon as possible. 1, peripheral neuritis: mainly symmetrical limb motor, sensory and vegetative nerve dysfunction. 2, polyneuritis: various sensory deficits are distributed in a glove sock shape, and can be accompanied by stimulation symptoms such as abnormal sensation, sensory hyperesthesia and pain. Lower motor neuron palsy in the distal limb, unable to perform fine tasks. The distal end is heavier than the proximal end, with autonomic disorders:, excessive or no sweating, brittle nails, and thin, dry or flaky skin. 3, paralytic brachial plexus neuritis: Most often seen in adults, often occurs after cold, flu, surgery. Performance of one side (a few bilateral) of the neck, scapula or upper limb muscle numbness, pain, weakness, muscle atrophy, proximal heavy, distal light. There is significant pressure pain in the upper and lower clavicular fossa or the axilla, etc. Pain is induced by traction on the upper extremity of the brachial plexus by abduction or supination. Hypesthesia in the shoulder, lateral aspect of the upper arm and radial aspect of the forearm. The biceps and triceps tendon reflexes are weakened or absent. 4, multiple peripheral neuritis: Most have a history of exposure to heavy metals (arsenic, mercury, lead), furacilin, isoniazid and other drugs, vitamin deficiency, diabetes mellitus, uremia and other medical history. There may be symmetrical sensory abnormalities (pain, numbness, hypersensitivity, hypoesthesia) in the distal extremities, often in the form of gloves and garters. Movement disorders, vegetative nerve dysfunction: cold, pale, cyanotic or sweating disorders of the extremity skin, the skin may be rough and thin, etc. 5, peripheral neuritis: symmetrical sensory, motor and vegetative nerve dysfunction mainly in the distal extremities. Initially, it is often characterized by abnormal sensory symptoms such as burning, pain and numbness in the fingertips or stimulation symptoms such as sensory hypersensitivity, and gradually hyperalgesia or even loss of sensation. The distribution of sensory disorders is glove or garter type. A small number of patients may have deep sensory impairment. 6, Raynaud’s syndrome: slow onset, usually after the cold. Especially in the fingers after contact with low temperature attack, more frequent in winter. During the attack, the skin color of the fingers turns white, followed by cyanosis. It often starts from the fingertips, and later spreads to the whole finger and even the palm of the hand. It is accompanied by local coldness, numbness, pinprick-like pain or other abnormal sensations, while the pulse at the wrist is normal. The attack lasts for several minutes and then resolves on its own. The skin turns flushed with burning and tingling sensation, and then turns to normal color. Local warming, rubbing, and waving of the upper extremity can often end the attack. The affected fingers are often symmetrical on both hands, and the little finger and ring finger are often the first to be involved. The little finger and ring finger are often the first to be involved, but the thumb is not involved, and the lower extremities are rarely involved. During the interictal period, there are no symptoms except for cold sensation in the hands and feet. In individual patients with severe disease, the attack is continuous and almost disappears during the interval. 7, enteropathic limb dermatitis syndrome: is a rare chronic skin disease. The main features of this disease are skin erosion, baldness, nail dystrophy and onychomycosis, and gastrointestinal dysfunction. The disease often occurs in infants from 3 weeks to 18 months of age. 8, cervical spinal stenosis: tingling and numbness in the fingers or arms, with initial onset of pain and numbness in the fingers (mostly at the fingertips) or arms, especially tingling. 9, cervical spondylosis: neurogenic cervical spondylosis severe paroxysmal severe pain, along the nerve root distribution of the lateral forearm and finger electric shock-like pain.
