Sore or tender fingertips

Introduction Peripheral neuropathy syndrome or zinc malabsorption affects the structure or activity of certain enzymes, resulting in certain metabolic disorders, symmetry damage of most peripheral nerves caused by various causes, mainly characterized by distal symmetry of the extremities Sensory, motor and autonomic disorders, diseases of lower motor neuron and autonomic dysfunction. The metabolic disorder such as tryptophan or fatty acid produces toxic substances, which causes the disease to occur.

Cause

The cause is still unknown. May be due to insufficient secretion of pancreatic enzymes. Metabolic and endocrine disorders Diabetes, uremia, hematoporphyria, amyloidosis, gout, hypogonadism, acromegaly, xanthomatosis, hemophilia, beriberi, pellagra, vitamin B12 deficiency Chronic alcoholism, pregnancy, chronic diseases of the gastrointestinal tract and post-operative, cachexia and burns caused by various causes. It has also been pointed out as recessive inheritance. In recent years, studies have shown that hereditary zinc deficiency has a certain relationship with the occurrence of this disease.

Electromyography CT examination

Diagnosis: toe pain, paresthesia of the extremities, poor coordination of the legs and feet, pain or tenderness of the fingers, hyperalgesia/limited limb pain, electromyography and nerve conduction velocity: if there is only a slight axis mutation, the conduction velocity Still normal. When there is severe axonal degeneration and secondary myelin loss, the conduction velocity is slowed down. The electromyogram has neurological abnormal changes. In the case of segmental myelin loss and axonal degeneration is not significant, the conduction velocity is invaded, but the EMG can be normal; determining the EMG and nerve conduction velocity contributes to the neurogenic damage and myogenicity of the disease. The identification of lesions is also conducive to the differentiation of axonal lesions and segmental demyelination lesions. The axonal lesions show a decrease in amplitude, while the demyelinated lesions show a slower nerve conduction velocity. Leg pain, more moving legs, feeling dull, feeling abnormal, numb fingers.

Differential diagnosis

Differential diagnosis of fingertip pain or tenderness:

1. Stinging and numbness in the fingers or arms: Patients with cervical spinal stenosis complained that there are fingers (mostly at the fingertips) or pain and numbness in the arm when the disease is first developed, especially tingling.

2, the forearm lateral and finger electric shock pain: the nerve root type cervical spondylosis is severe paroxysmal severe pain, along the nerve root distribution outside the arm and finger touch electric pain.
