The cause of tendon sheath cyst is degeneration of connective tissue around joint capsule. Overwork, repeated stress and infection may all be the causes of tendon sheath cyst. Most patients are young people, and women are more likely to get sick than men. The causes of tendon sheath cyst are overwork, osteoarthritis, some systemic immune diseases, or infection. Some occupations that require long-term repeated joint strain, such as typists, cargo handling or industries that require long-term computer operation, can cause tendon sheath cysts.

Tendon sheath cyst will have slight pain, and the cyst fluid will become hard and soft after a long time. If the affected part is in the wrist, it will be accompanied by wrist weakness, discomfort or soreness, radiation pain, and even cause certain dysfunction to the patient in severe cases.

There are many treatment methods for tendon sheath cyst, which can be crushed and absorbed slowly, but there are many cases of recurrence after this treatment, so the effect is not very ideal. The surgical treatment of tendon sheath cyst is expensive and will affect the activity of the affected joint for a long time.

It is convenient to recommend TCM diagnosis and treatment.
