I am 40 & was DX last year with autoimmune thyroiditis.
I am now up to 100 mg of levo which seem's to be my optimal dose. My TSH at DX was 14 & now It's 1.6, the lowest it has been since DX.
Since my 20s I have suffered from palpitations due to anxiety on & off but did at that time have an ECG & scan which showed no structural abnormalities of my heart, so I just learned to ignore them & they didn't worry me until now . I tend to get them more at night or when I am tired or anxious but for the past few days I have been suffering from the palpitations in the day & at night & they are more frequent then I am used to. I wasn't feeling particularly anxious when they started but maybe a little tired, having not slept well the night before. It has been a few days now & they are not completely going away, despite having slept well & laying of all caffeine except green tea!
The thing is, I am fine until they do start, then I start worrying about them again, probably making them worse, so it's a vicious cycle!!
My question is, could these increased palpitations be down to my lower TSH (1.6, bloods taken beginning of Aug?) I have been on 100 mg of levo since last Christmas so thinking it's not the levo as surely I would have noticed these increased palpitations before now?
If any one can shed some light on this I would be very grateful as I am starting to worry about them a lot now. Thanks.
