We are not specialists, or doctors of any kind. We are simply patients like you. Some of us have been dealing with thyroid conditions for many years and have done a lot of research and are very familiar with thyroid conditions. We're here to help in any way we can.
Did your doctor order thyroid function tests, such as Free T4, Free T3 and the pituitary hormone test, TSH? If so, please post those results, with their corresponding reference ranges.
If your iodine absorption test showed only 3%, that would indicate your thyroid is not working well (producing hormones) and you need to be on replacement hormones. Did your doctor prescribe you the necessary hormones? If so, please tell us what hormones he prescribed and what dosage.
Is the pain in your neck, the only symptom you have? If you have other symptoms, please tell us what they are.
