Neck cysts need to be treated according to the cause of the condition. Fluid extraction treatment can only draw out the pus from purulent inflammation, which does not help much in recovery, and is generally not recommended. Neck cysts can be caused by sebaceous cysts, thyroid nodules, lymphocysts, etc., and the symptoms will be different depending on the cause. 1. Sebaceous cysts: Sebaceous cysts are cysts caused by the accumulation of sebum, which are generally benign skin diseases with localized redness, swelling, pain and other symptoms, and are generally of little help when treated with fluid extraction. Most of the cases will not be removed, but if the disease is more serious, it can be surgically removed. 2. Thyroid nodule: if the goiter is caused by iodine deficiency, iodine supplementation treatment is needed; if it is infected goiter, anti-infection treatment is needed; if it is tumor hyperplasia, observation is needed; if the cysts are large and symptoms such as pressure or pain appear, resection and pathological examination are needed before receiving other treatments. 3. Lymphatic cysts: lymphatic cysts have more causes, most of them can be found in early childhood, and usually surgical resection will be taken to a certain extent. If neck cysts appear, it is recommended to go to the hospital in time and actively cooperate with the treatment under the doctor’s advice.
