1, usually pay attention to the protection of the wrist joint, foot small joints, etc., to avoid strain, especially like in the office to work, the use of computer frequency of white-collar workers, more time to pay attention to the combination of work and rest, more relaxed wrist, so as to avoid long-term chronic injury to the synovial cavity synovial fluid increased to form cysts. 2, tendon sheath cysts within the capsule is filled with liquid, can be extracted with a needle transparent jelly-like material, so you can use pressure to apply force, the cyst will be squeezed, let it heal itself. This method is relatively easy, but the radical effect is not good, and there is often a recurrence of the situation. 3.Flex your wrist or foot towards the opposite side of the side with the cyst, for example, if it grows on the dorsal side of the wrist, flex your hand palm downward so that the skin on the surface of the cyst becomes tense, i.e. the cyst wall also becomes tense. Push the cyst block around with fingers for a few minutes to release the adhesions with the surrounding area, then push the cyst to one side with force by thumb and squeeze it, after hearing a loud sound, it means the cyst has broken. At this time, let the patient often massage the part where the cyst existed before to avoid recurrence. 4.Some cysts are not very volatile and have a hard texture, so if you simply squeeze them with your fingers you may not be able to break them. In this case, you can change the method by first disinfecting the skin outside the cyst and then piercing it into the cyst with a small-sized needle, at which time you should feel whether there is a falling sensation of penetrating the cyst wall. When the puncture is successful, the needle is removed and the cyst contents are then squeezed out with force by the thumb. Then massage to make the cyst disappear. 5. In addition to the massage method, after the cyst contents are discharged, hormonal drugs can be injected into the cyst cavity, commonly used are prednisolone acetate, followed by bandage with pressure. Under the effect of medication and bandage, adhesions will be made between the walls of the bursa, and then disappear. 6. For cysts that cannot be treated with massage, puncture or drug injection, or cysts that recur many times, non-surgical treatment, since it is ineffective, can only be performed by cystectomy.
