Itchy thyroid nodules are often caused by further enlargement of the thyroid nodule and need to be examined by the general surgery or head and neck surgery department of the hospital, because when the thyroid nodule increases in size it can cause local itching, pain and other uncomfortable symptoms. If the disease is considered benign and the swelling is not large, it can be followed up and observed. If the mass is large and considered to be malignant, it needs to be actively examined, surgically removed, and fast pathology done. If the tumor is considered to be malignant during surgery, radical surgery of the tumor is required, followed by relevant treatment after surgery. During the examination and treatment period, avoid eating too spicy food, such as chili, spicy fries, spicy hot pot, etc., and do not drink alcoholic beverages, because these will lead to local discomfort and affect the examination results and treatment.
