At least I think it's because of the flu jab as my left arm didn't start aching until a few days after the injection. I had both flu and covid vaccines together on Oct 27th and my arm is still aching quite a bit when I'm using it and has got worse this past few days if anything. I rarely get an aching arm after a flu jab and when I have it's just for a couple of days not over a fortnight like this one.
Has anyone had a prolonged aching arm after an injection like I'm having?
