For the last few days have been experiencing a lot of palpitations and its really scary. My last results on 17 May were serum ferritin 56 (12-230), free T4 9.8 (12-22), free T3 (4.4 (3.1-6.8) and TSH 1.67 (0.3-4.2). I was on 1.5 grains Thiroyd NDT and since then I have gradually raised to 2 grains NDT spread into 4 doses approx every 3 or 4 hours throughout the day. I take ashwagandha and rhodiola along with other B Vits, magnesium, selenium, zinc for support. I had been doing well and feeling good but then this started up. I have been having more stress than usual, teenagers, Mum with dementia, divorce, etc and haven't found much time for even a walk. The doctor after the test results said I should take T4 levo and wrote me a prescription which I haven't taken. Any thoughts would be appreciated, not sure which way to turn. I have been addicted to about 3 bananas during the day, they seem to make me feel better but taken avocados instead as I am putting weight on. Maybe this has something to do with it. The palpitations seem to be worse late afternoon, evening time.
