In clinical practice, it is common to encounter patients who present with abnormal masses that are palpated or touched by the physician. Some are normal abdominal structures, while others suggest abnormalities or disease, and care should be taken to discern whether the problem is pathological or physiological. Tenosynovial cysts can occur at any age, mostly in youth and middle age, and more often in women than men. The cysts are slow growing, round, and generally do not exceed 2 cm in diameter. they are also found suddenly. A few of them may recede on their own, or they may grow again. In some cases, except for the local swelling, there is no conscious discomfort, and sometimes there is mild pressure pain. In most cases, there is localized soreness or discomfort that affects activity. Prevention: Tenosynovitis requires rest for the affected area. Since tendovaginitis is an inflammation caused by repeated excessive friction, those who have suffered from this disease must avoid excessive manual labor in the way. Prevention attention to correct transplantation of posture at work to avoid excessive strain on the joints regular rest. Computer people should beware of tendon sheath cysts Tendon sheath cysts are common in women and adolescents, which occur near the joints or tendon sheaths, with the highest incidence in the dorsal wrist, the flexor wrist tendon on the palmar side of the wrist and the dorsal foot. Chronic injury increases the synovial fluid in the synovial cavity and forms cystic herniation or connective tissue mucosal degeneration is an important cause of morbidity. People who work with computers for a long time, hold the mouse for too long, or incorrect posture, can lead to injury to the synovial cavity of the hand joint, and cause disease.

When other methods of treatment are ineffective, the tendon sheath cyst may be surgically removed. Strenuous activity of the affected joint should be avoided for 1 month after surgery. The modern acupuncture treatment for this disease was first seen in 1958, when moxibustion with ginger was used to achieve better results. Since the 1980s, there have been many reports on various acupuncture point stimulation methods for this disease, and on the basis of the inheritance of the previous methods, fire needling, pointer, acupuncture plus jar and acupuncture point injection have been added. In order to prevent recurrence, local pressure after acupuncture is generally advocated. From the existing experience, acupuncture is indeed one of the better conservative treatments for this disease. Western medicine believes that this disease is mostly related to chronic strain, mechanical irritation and trauma to the joint or tendon sheath.
