Pain after thyroid surgery will last 3-7 days, depending on the extent of the surgical injury, the patient’s tolerance of pain and post-operative care. The effects of anesthesia will wear off after thyroid surgery and the patient will experience pain. Post-operative oozing of tissue fluid can irritate the incision and cause pain. If the postoperative dressing is too tight, it can also irritate the incision and cause pain. As different patients have different levels of pain tolerance, the duration of postoperative pain will be different. Patients who are less sensitive to pain will have a relatively short duration of postoperative pain. Patients who are less sensitive to pain will have shorter postoperative pain. If the patient is more sensitive to pain, the duration of postoperative pain will be slightly longer. If infection occurs during the recovery period due to improper care, the wound recovery time will be longer and the pain duration will also be longer. Change the medication after surgery to prevent infection. If the pain is particularly obvious, you can follow the doctor’s instructions to take some painkillers to control. After the operation, you should go to the hospital on time for rechecking, and tell the doctor in time if there is any discomfort after the operation.
