Hi: My 18 year old daughter was diagnosed with thyroid cancer a little over a year ago. She had a partial thyroidectomy and noticed this morning that where her incision is, really hurts. We live in Hawaii and she is at college in Seattle, WA. she said her pain is 7-8...what could it be? Just a little background: my younger daughter, who is 16 now was also diagnosed with thyroid cancer, but hers more advanced, she had a thyroidectomy two months after my older daughter.
