Should I get a second opinion and be retested for possible thyroid problem?

Read anything related to thyroid problem symptoms and you will see your symptoms all over the map. Additionally it is a common problem and mistake of health care professionals make - disagnosing you as depressed and a mental case when you are hypothyroid. It is important what your numbers were - a TSH above 2 should be treated with thyroid hormone. Additionally it is possible that your numbers are "normal" but usually no one checks for TPO which is thyroid peroxadase antibodies which are indicator of an autoimmune disease that could be just beginning. In this case your lab results are normal because it takes a long time for the antibodies to grow in numbers and distroy your thyroid. Yes - blood tests are very expensive. And asking for more blood work will result in spending more money on this. However, you have to do this in order to find out the underlying cause of this. Also, you might want to keep your calories in the 1500 range per day and eat more veggies and protein vs. carbs. This will also help you to manage your weight. The bottom line is - you need to listen to your body and your symptoms. If you do not feel right, you need tell the doctor or nurse that you need additionaly istance as you are not improving. it is important that you research the lab results "we call normal" on the internet. (try about.thyroid.com) and match your lab work to it. If your TSH is below 2 and your other thyroid hormones are within the range then check your antibodies. If you have antibodies over 30 that means that your body is creating antibodies against your thyroid and it will slowly destroy it. Only with thyroid hormone you can reverse that and by supplementing what your body is not making or failing to keep in internally balanced. If your TSH is below 2, your other thyroid hormones are in range and your antibodies are below 30 you are lucky and healthy and at this point do not have to worry about thyroid issues. As far as your symptomps - you might want to address them one by one and make lifestyle modifications which may help you with each as at that point you know for sure that your thyoid is not the culprit. However, thyroid and the adrenals are closely connected and especially if you experience fatigue and tiredness you might also want to check your adrenal functions. I wish you good luck and good health!
