Case: Mr. Sun, 55, recently developed a cyst on his wrist, which was particularly obvious and hidden by pressing it with his hand, without pain or itching. When doing work, it would become swollen and painful. Mr. Sun was worried that such a cyst would not bring harm to his body. Many people in life often have swollen and painful fingers and wrists, which is actually a common clinical manifestation of tendon sheath cysts. This is a common clinical manifestation of tendon sheath cysts. When people rub their joints for a long time and excessively, there is a possibility of damaging inflammation of tendons and tendon sheaths, causing swelling and pain and limiting the movement of the patient’s wrist. However, generally, cysts are benign swellings that do not affect the body except for the appearance, so there is no need to worry too much; if there is pain in the wrist joint, it is possible that the cyst is increasing and compressing the nerves or blood vessels in the hand, so surgery is urgently needed to avoid affecting joint activities. Tendon sheath cysts are the most common type of mass that occurs in the soft tissues, usually around the tendons and tendons. They are attached to the joint capsule or within the tendon sheath and often communicate with the joint cavity. The wall of the capsule is dense fibrous tissue with an inner layer of white smooth synovial membrane, which can become hypertrophic over time and contain colorless and transparent gelatinous mucus. The growth of the cyst is slow, the pathogenesis is not yet clear, and there is some relationship with chronic traumatic stimulation. Tendon sheath cysts are found on the dorsal side of the wrist, the palmar side of the wrist, near the distal palm of the hand, on the back of the foot, and at the front of the ankle. Hemispheric bulges or globular swellings are unintentionally found in these areas. Some may have mild joint weakness or soreness, with significant soreness on firm pressure on the bulge. There is a sense of firmness and elasticity, which may feel hard over time. Tendon sheath cyst disease occurs most often in occupations that cause long-term repetitive strain on the joints, such as typists, cargo handling, or prolonged computer operation. For patients who already have tendon sheath cysts, attention should be paid to resting the affected area. Since tendon sheath cyst is an inflammation that can be caused by repeated excessive friction, people who have suffered from this disease must avoid excessive manual labor. Pay attention to the correct working posture of the hand joints, avoid overstrain of the hand joints, and be sure to take regular breaks. When you have time, often use hot water to soak hands and feet, so that the local joint Qi and blood flow, blood circulation; hand and foot joints after frequent use, should be timely activities, or from shallow to deep massage, as a way to relieve pain at the hand bone joints. Through the above introduction, I think many friends on the wrist tendon sheath cyst how to treat the problem of understanding. The recurrence of wrist tendon sheath cyst is a characteristic of wrist tendon sheath cyst, so after treatment, pay attention to good habits and health care to reduce the chances of recurrence, and thus better avoid a series of impact on work and life.
