About 3 months ago, I started experiencing heart palpitations at night. A few times a minute, my heart would have a single strange beat, almost like a twitch in the heart muscle. This got worse over about 3 weeks, with twitching every so often. After 2 weeks, I went to the ER to make sure I wasn't going to die. They did blood tests and an ECG (during the ECG, the palpitations weren’t happening), and they said everything seemed fine. After the visit, the palpitations decreased over about 2-3 weeks, but the twitching started to increase, reaching a point where it was almost constant for a few days—mostly in my eyes and face, but also in my legs, hands, and stomach. Now, the twitching doesn’t happen every day, and the heart palpitations only happen a few times a day.
When it started, I was weaning myself off synthetic T3/T4, and by the time I went to the ER, I had been off thyroid medication for ~2 weeks. Now I've started NDT (8 days ago), but it hasn’t made any noticeable difference. So far, I’ve tried pregnenolone, progesterone, magnesium glycinate, taurine, aspirin, vitamins E, A, K, and D, and a B complex—none of these have helped to any degree. Almost every day, I drink 1/2 gallon of 1%/skim milk and 3 cups of orange juice, and I occasionally eat beef, so I don't know of any deficiencies but my diet isn’t completely free of toxins/additives. Here are the results of the ER blood test:
