Lasers do not treat finger joint cysts. Finger joint cysts are mainly treated by conservative treatment and surgery. 1. Conservative treatment: If the cyst is small, it is often fixed with fingers and pressed locally to break the wall of the cyst. Because the whole wall of the cyst will be torn open after squeezing, the cyst will disappear after the fluid is squeezed out. After squeezing, put gauze on the wall and put pressure on the bandage, so that the wall of the cyst can be closed and healed. It can also be treated by puncture and injection of hydrocortisone into the cyst. 2. Surgery: For particularly large cysts of the finger joints, which affect the function of the joints and seriously affect the daily life, surgical treatment can be adopted, in which the entire wall of the cyst is completely separated after incision and then removed. In summary, laser treatment of joint cysts is not yet available clinically. It is recommended that if you suffer from finger joint cysts, you should go to a regular hospital in time, follow the doctor’s instructions for timely treatment, and do not use your own medication and treatment, so as not to cause adverse consequences.
