I got my first dose about 4 weeks ago and have been curious about the main side effect I had from it and if it was generally normal or not. I'll be getting my 2nd dose at the 8 week mark in December.
Background - I'm a normal weight, maybe 10-20lbs heavier than I like, but by official standards I am "normal" and not overweight. I also have a very sedentary lifestyle with a WFH job - not a whole lot of exercise the past few years thanks to still being in my own version of "lockdown".
My side effects only lasted about 4-5 days. General sore arm, lots of sleeping and naps, and just feeling kind of tired and not wanting to do anything. These specific side effects I'd give a 2/10 on the bad scale. Not a big deal and, other than wanting to sleep a lot, no problem working after the first full day after the vaccine although I did take 2 half days to sleep.
The other side effect that concerned me was a pounding heart. Even laying down in bed at night it just pounded through the back of my chest into my mattress. It didn't feel like a super fast heart beat, just very heavy. I also did a few dishes and it would start pounding. This lasted about 2-3 days, I think, and then went away completely.
Now, full disclosure, I was terrified to get the vaccine. Like almost full blown panic attacks the few nights before. I was also terrified after when anything in my body felt a little off. So, I'm not sure if I caused the heart pounding or the vaccine. But, the fact that it did it two nights in a row while trying to fall asleep worried me. It would also do it throughout those days, randomly.
One reason I think it may have been in my head, or just a coincidence, was that I was actually in the process of returning my fitness tracker (with heart monitor) at the time and getting a replacement. I got the replacement back on day 4 or 5, and that's when the heart pounding stopped. I haven't had an issue since.
I guess I'm looking to see if this heart pounding (palpitations, possibly?) is normal as I'm sure I'm going to freak out again on the 2nd dose. At what point would the heart pounding be a cause for concern? I'll have my fitness tracker this go-around to track my heart rate. Would a cheap blood pressure monitor from Amazon be helpful?
