I am very concerned about my symptoms -- coughing, throat irritation, fatigue. And I am most of all worried about cancer. The doctors I have consulted in Wilmington NC don t seem to know anything about thyroid problems -- hypothyroidism, hyperthyroidism, or lupus. I need help and expert opinions. I am 74, married, fair health. Any advice you can offer will be very valuable to me. Thanks and God bless you!
