I received my flu shot last night, and not for the first time, however I woke up in the middle of the night extremely nauseated and on the verge of being sick, and that’s not even worst part, the worst of it is the soreness and aches overtaking my entire body. At this point I can’t remain in the same position for over a few minutes without becoming so uncomfortable. I went for a walk to my car and I was absolutely exhausted. I’ve never experienced symptoms like this after a shot, and I’m concerned because all the side effects I’ve been reading about say “mild aches and pains”, but this is not mild, I’m not even able to make it off the bed let alone to work. My back, shoulders and hips are the worst in particular. There is also a headache included in all of this. Why is it affecting me so badly? Should I be concerned?
