burning pain
Introduction
Introduction Burning pain is caused by the intense and long-lasting burning sensation of the local skin surface caused by incomplete peripheral nerve injury. Postts first reported the trauma caused by this disease in the late 18th century. Mitehell identified the term "burning pain" in 1972. The whole course of disease is continuous, often upper limbs are more common than lower limbs, more common in the median nerve and sciatic nerve injury, about 50% of patients with pain at the beginning of the injury site, and later limited to the distribution of the affected side of the nerve.
Cause
Cause
Nerve damage:
In the case of larger nerve damage, the early incidence of burning is about 20%, but only 5% of patients have a longer disease. This is because the damaged nerve contains a large amount of sympathetic nerve fibers or the damaged nerve conductance has not been completely destroyed, or the vasotoxic substances are released to the nerve endings due to trauma and the thalamus is excessively stimulated.

Skin lesions
Anal burning pain check:
1. Digital rectal examination and endoscopy: For the diagnosis of an anal fissure that is difficult to diagnose, rectal examination and anal microscopy may be performed as appropriate, and the operation should be gentle, so as not to cause severe pain to the patient. 2. Histopathological examination: For chronic ulcers located in the lateral position, it is necessary to consider whether there are rare lesions such as tuberculosis, cancer, Crohn's disease and ulcerative colitis, and biopsy can be used for differential diagnosis.Diagnosis
Differential diagnosis
According to the medical history, after the exclusion of central nervous system disorders, the diagnosis is not difficult. The central nervous system consists of the brain and spinal cord (the brain and spinal cord are the central parts of various reflex arcs) and is the most central part of the human nervous system. The central nervous system receives incoming information from all over the body, and after it is integrated and processed, it becomes a coordinated motorized efferent, or stored in the central nervous system to become the neural basis of learning and memory. Human thinking activities are also functions of the central nervous system.
Generally not confused with other diseases.
