Thyroid nodules are mostly benign nodules of the thyroid gland. After surgery, the stitches are usually removed 5 days after surgery, and the patient can return to normal in about two weeks after surgery, and can perform normal activities or go to work. It is important to avoid strenuous activities and to limit the activities of the neck, because it may affect the recovery or healing of the wound. After surgery, you should also pay attention to the diet and structure, do not eat too much spicy food, stimulating food, pay attention to the soft diet. The pain can be caused by swallowing too much raw, cold or hard food. After the surgery, it is also necessary to review the thyroid ultrasound regularly, because the cause of thyroid nodules is considered to be related to the unreasonable structure of the diet, appropriate supplementation of iodine-containing foods, and if necessary, oral thyroxine tablets for treatment, and to monitor the changes in thyroid function.
