much delayed reaction to flu shot

[mellowtigger]

I got my flu vaccine 2 weeks ago, October 17 Monday. This morning, the injection site is sore for the first time. That seems weird?

I have not encountered that before!

Yeah, first thing at consciousness this morning was the thought that my arm hurts slightly. I tend to sleep on my side, so I figured that was it. But I quickly realized it wasn't the socket. An hour later, it's still there, farther down my arm definitely in the "meat" of the bicep. Strange.

That reminds me of this article:
https://www.psychologytoday.com/intl/blog/heal-the-mind-heal-the-body/202101/what-s-the-new-phenomenon-called-covid-vaccine-arm

But that was for the Covid vaccine, not flu, and was one week later, not two.
The follow-up at the end of the article does mention 2 people who had the delayed reaction on day 14 and 15.

Very interesting. Thanks for the link! The weird sensation in my arm lasted only about half of the day, and now it's fine again. I never did see anything odd at the surface.
