If you want to do anything that involves the arm you get you flu shot in, make sure to schedule your shot for when you have nothing going on for a few days.
Yesterday, Larry and I went over to Walgreens to get our flu shots. The shot felt more weird than I remember going into my muwcle but the bad part was that 3 hours later I felt like I had damaged my shoulder in some way. I couldn't figure out why it was hurting so much or why it was so hard to move my arm. About a half hour later I remembered I had gotten that flu shot.
When I came home I asked Larry if his arm hurt and it did in the same way. I usually feel a little sore after but he doesn't. Now we both did. Hoping it will go away in a few days and not turn into a case of SIRVA which I never heard of until I looked up shoulder pain after flu shot.
