I saw an endocrinologist for the first time today, and I've come away feeling absolutely baffled! She was very nice and listened to everything I had to say regarding my symptoms and history. She even agreed that taking T3 would be an option if my test results suggested it was appropriate. However, she thinks that, looking at my test results over the last 18months, I may not actually be hypothyroid! I'm not autoimmune anyway, but she thinks my symptoms could be caused by taking levothyroxine, and that the real problem could be my pituitary. I'm now waiting for an MRI and a cortisol test, along with another thyroid panel.
