Tendon sheath cysts are not recommended to be punctured with a needle by oneself. Patients with tendon sheath cysts need to consult a doctor in time, who will diagnose and treat them accordingly with observation methods, medication, general treatment or surgery. If the tendon sheath cyst is punctured by oneself, it may lead to infection of the localized lesion and the nearby tissues, and in serious cases, it may even lead to localized impaired mobility, resulting in further injury. If the infection is not treated properly, it may spread and even cause systemic symptoms. Therefore, it is recommended that the patient should go through formal treatment after consultation. 1. Observation method: For patients who only show superficial masses, usually no special treatment is needed. At this time, patients need to carry out appropriate joint braking under the guidance of the doctor, so as to reduce the movement of the diseased joints and avoid further aggravation of the injury; and conduct regular review. 2. Medication: For patients with pain, vascular or nerve compression, medication is often chosen. Drugs should be applied under the guidance of doctors. (1) Glucocorticoid drugs, such as prednisolone acetate. With anti-inflammatory, reduce inflammatory material exudation and other effects, this drug needs to be injected into the cyst cavity after the cyst contents are discharged by a specialized doctor, and pressure bandage is applied. (2) Non-steroidal anti-inflammatory drugs, such as celecoxib, can relieve pain and reduce inflammation. 3. General treatment or surgical treatment: some patients with heavy compression symptoms and pain, affecting aesthetics, can choose general treatment such as puncture injection method, and if repeated recurrence can choose surgical treatment to remove the cyst completely. It can relieve patients’ symptoms, improve their quality of life, and improve the unattractive appearance caused by the lesion.
