Rationale: Tingling around the mouth should be reported immediately as it may indicate hypocalcemia, a serious complication resulting from accidental removal or damage to the parathyroid glands during thyroidectomy. Hoarseness and difficulty swallowing are common post-thyroidectomy symptoms related to the surgery itself and the manipulation of the vocal cords and nearby structures. Numbness in the fingers is not typically associated with immediate serious complications of a thyroidectomy.
