Flu Shots and Nurses

I got a flu shot yesterday. First of all, the nurse did not wear a glove while injecting it AND while wiping away the blood. Second, I've never had a flu shot that hurt...or bled. I just can't find a good nurse in that place. Today I feel like I have the flu. Not only that, but my arm hurts and I can't raise it without cringing. I also couldn't sleep on my left side last night, which is pretty much the only comfortable position I can sleep in these days.
