New to this. I was diagnosed in 2011 with Hashimoto, and multinodular thyroid. Had to start with a new doctor recently who took away the hashimoto diagnosis because my levels are within the normal range. My TSH levels bounce all over the place with resent levels on the low normal 0.7, my FT3/T4 are also on the low normal. I do have ultra sounds done every 6 months to monitor the growths. Recently I have been experiencing feelings of muscle weakness, fatigue, and extreme intolerance to the cold. I'm wondering if these new symptoms could be thyroid related.
