I recieved my shot on Monday, 3 days ago. The injection site looks like a large bug bite, hurts and itches. The day of the shot two others got one when I did. All three of us had a stiff neck within 5 hours. I have since had diareah(sp), which may have nothing to do with it. Three hours ago my shoulder started hurting, it is very painful and started out of the blue. If I am still I am fine, if I move it at all it is painful. I have done nothing to cause an injury. I have to say that I felt before I found this forum, it had something to do with the flu shot. The reason it is the same arm, came hard and fast out of the blue and my neck started acting up again today, just the slightly stiff feeling I had the day of the injection.View Thread
