Generally speaking, small needle therapy is more effective in treating tennis elbow. However, the exact effect varies from person to person. If necessary, it needs to be combined with other measures for treatment. It is effective in treating the sequelae of various soft tissue injuries and the sequelae of damage to the locomotor system, such as cervical spondylosis, lumbar intervertebral disc herniation, chronic lumbar muscle strain, frozen shoulder, tennis elbow and so on. However, it should be noted that because the small needle knife therapy does not need to cut the skin, the doctor can not visualize the level of lesions, the operation is difficult, and it is easy to damage the surgical site of blood vessels, nerves, etc., thus causing injury. Tennis elbow, i.e. epicondylitis of the humerus, is a chronic inflammatory disease. Non-surgical treatment has a certain effect on the vast majority of patients. If the pain is more serious, closed therapy is feasible, and relief can be obtained by injecting drugs at the pressure point. If the pain is still persistent after the application of medication and restriction of activities, surgical treatment can be reconsidered. Patients are advised to seek timely medical examination to clarify the cause of the disease and target treatment and management.
