Itchy thyroid nodules are often caused by further enlargement of the thyroid nodule and need to be checked by the general surgery or head and neck surgery department of the hospital, because when the thyroid nodule is enlarged it can cause local itching, pain and other uncomfortable symptoms, and in the hospital the doctor will usually further check the neck ultrasound or neck CT, as well as thyroid function and thyroid nuclear scan. If the swelling is considered benign and not large, you can try oral medication such as levothyroxine tablets. If the mass is large and is also considered to be malignant, aggressive improvement of examination, surgical removal and rapid pathology are required. If the tumor is considered to be malignant during surgery, radical surgery of the tumor is needed, followed by related 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.
