Muscle pain after total excision may be caused by the surgery or by reasons other than the surgery, and needs to be dealt with according to the cause. The cause of muscle pain may be due to the fact that the parathyroid glands are in close proximity to the thyroid gland during the operation, and may be accidentally injured during the total excision, resulting in disturbances in calcium and phosphorus metabolism, which may cause a decrease in calcium levels, numbness and pain in the limbs, stiffness in the hands and feet, and even muscle spasms. In this case, you need to go to the hospital and have your blood calcium and phosphorus levels checked. If the blood calcium is too low, calcium supplements are needed to relieve the symptoms. However, muscle pain may not always be caused by thyroidectomy, but may also be caused by myositis, metabolic diseases or muscle ischemia, as well as medications, autoimmune diseases or psychiatric conditions.
