Chest pain: It is hard to answer your question, other than to say "see your doctor". If your thyroid blood tests are indeed normal, then the symptoms are not from that. Is this anxiety? Or is it from coronary artery disease. See your doctor. ...Read more

I have normal levels lab work except free T4 high. I had thyroid scan it showed hyperthyroidism not graves. Why isn't it showing in my lab work?

I have normal levels lab work except free T4 high. I had thyroid scan it showed hyperthyroidism not graves. Why isn't it showing in my lab work?

Confusion: A thyroid scan cannot diagnose hyperthyroidism, only lab tests and doctor can. Graves' disease is a type of hyperthyroidism. Free T4 is usually not as accurate for diagnosis as tsh. Thyroid "uptake" may have been done with scan and can be elevated for several reasons other than hyperthyroidism, such as thyroid inflammation. See your doctor and/or an endocrinologist. ...Read more

I HAVE HYPERTHYROID (GRAVES) I AM ALLERGIC TO ANTI- THYROID DRUG. I broke out in hives last year MY CURRENT LAB RESULTS ARE SCARING ME. -JOHVANA?

I'm scared too: Please forgive my frankness. If hyperthyroidism isn't managed, you can go into thyroid storm and it's a coin toss whether you die. You got hives from your meds? You may need to take them anyway -- OR you may need to accept therapy with radioactive iodine. If you're resisted this in the past, it's time to reconsider. If it's not been offered, ask why. ...Read more
