I'm already on Synthroid for my hypothyroidism and it didn't help me with my energy level or other symptoms they added Cytomel. I had to discontinue that almost immediately (3 weeks) because my heart rate wouldn't go below 90 bpm (even on the lowest dose). Is there anything that will help my other symptoms? 1-lethargy 2-hair regrowth 3-swollen ankles 4-weight 5-lethargy (I know I mentioned that 1st but it's so bad that I have no energy to exercise).
