I was diagnosed with Thyroid Goiter about two years ago. At the time of diagnosis my thyroid hormone levels were "within range", according to any Dr. I spoke with. My symptoms are Excessive sweating, heat intolerance, wight gain, anxiety, extreme fatigue, irregular periods, I had some trouble getting pregnant (almost 1 year), Finally, I found a new doctor who prescribed me Synthroid 88 mcg and said every symptoms was due to the thyroid. I took Levothyroxine 88 mcg and started to have more energy and my menstrual cycle began to be more regular about 4 weeks into therapy the other symptoms stayed the same. 3 months into it the fatigue and irregular periods came back. I had to find a new Dr. due to mine closing his office. She suggested to take the name brand Synthroid. So I do now but no change. Recently my husband took me to the hospital, I was delusional, my heart rate was 144 at rest, I was sweatingand my face felt sunburned. I went back to the doctor and she requested more bloodwork and a 24 hour urine for catecholamines, VMA, and metadrenaline. All fine. My husband thinks I need mental help but I just don't know what is wrong. Any suggestions????
