Around 1:30-2:00 today my right wrist started hurting. Seemed kinda out of the blue. I took some Tylenol but it didn't seem to help by 4:00 it hurt into my for arm up to my elbow and now it's up further to my shoulder. I am 7w6d and I got the flu shot in my right arm yesterday. Think I have anything to be worried about or its just the shot?
