I just got labs back that the new (doubting Thomas) endo ordered, and saw my PCP about them today. This is my new endo, who told me I was probably gaining weight because had a steroid shot in my foot, that by increasing my meds to raise my FREEs, I will give myself a heart attack and am destroying my bones. My PCP just shakes her head, but says she is at the limit of her knowledge about thyroid. She has tested my heart, and it's fine.
