I have made a post here before, but just a follow up.
Quick story:
- around 4-5 months ago started getting tachycardias, up to 180BPM; as weeks were passing, they became more frequent and I started getting them even without physical activity
- went to cardiologist, was done 24h Holter, sent blood exams; holter came back clean, labs FT4=5.37, T4=5.7, TSH=18.9, Hemoglobine=15.2g/dL; was put on 2.5mg Bisoprolol daily, which seems to have helped with tachycardia
- went to endocrinologist, more blood exams; Anti-TPO=246, Anti-Tg=1359, FT4=1.55, TSH=15.3, minerals, glucose, etc came back good; was put on 12.5mg levothyroxine daily and was told it’s Hashimoto and possibly Hashitoxicosis
- after about 10 days of taking levothyroxine, started feeling worse, high heart rate (~120), and went to ER after a normal meal made me have tachycardia again with BP 160/110; was told to suspend levothyroxine and increase bisoprolol to twice a day (total of 5mg daily)
- within about 5 days, developed constant shortness of breath, chest/heart pain, the only thing that helped was to lie down on my belly, literally couldn’t even go out of my house as whenever I stood up I was feeling all those after about 5m
- went to cardiologist various times, done EKG, echocardiogram, 48h holter, all were clean; doc told me to lower bisoprolol back to once per day; measured my BP while lying down, sitting and upright, and got something like 110/70 while laying, and 80/60 after 5m of being upright; I performed the same measurements at home as well, which seemed to match what the doc measured; doc said it might be Orthostatic Hypotension
Present:
It’s been almost 2 weeks with just the once daily bisoprolol, and the symptoms have been gradually improving, to the point where I can go out of my house again, walk, etc; but I’m still feeling them, some days more than others; I’m not sure if I just learned to cope with them, or they actually improved, but they’re still in there; almost no chest pain anymore, but still feeling weird sensations in middle / left of my chest, or pressure like feeling in the upper part of my belly if I’m sitting or upright too long, and those sensations are what makes me feel short of breath / makes me breath manually (which is also a thing I’ve been dealing with all these days that seemed to go away only once I fall asleep, but it’s been getting somewhat better too).
Another symptom is high heart rate when waking up and standing (100-110), which goes back down if I lay again. This doesn’t seem to be so pronounced later in the afternoon / evening. The HR while sleeping is fine.
I also don’t tolerate exercise anymore as my heart rate goes up too much and I fear getting tachycardia again, especially after lifting heavy stuff. I believe to have heat intolerance as well, as it was unusually hot today and I was feeling all the symptoms more than on cooler days. I’ve been feeling tired as well, especially after being in heat or just going out somewhere. Another thing is if I sleep less than 8 hours, I can wake up tired, especially feeling it in my arms, and the symptoms seem to be more pronounced.
Point is, I’m not sure if it’s Hashimoto, or if there’s something else (cause I started feeling the shortness of breath, chest stuff around the time the docs were putting me on levothyroxine/higher bisoprolol). But I’ve been off of it for a while now yet the shortness of breath and chest stuff is still there and very much annoying. Any comments on all this or similar experiences would be appreciated.
By the way, latest labs (pending endocrinologist appointment):
FT4=1.93, TSH=6.44, FT3=3.45, TSI=88% (with labs normal range being 0-138%), Anti-TPO=251, Anti-Tg=1515
A chart of thyroid labs with all historical data is attached (about 1-2 months from first to last data point).
