Got my flu shot yesterday and everything was fine! My arm is sore but that’s normal. Well this morning I woke up did my morning routine with my daughter we ate breakfast but now all of a sudden I can’t stand up longer than 5 mins, I’m getting so nauseous and weak I have to just sit down wherever I am. What could be going on? It would be exactly 24hrs since I got it and now all of a sudden all these side effects are hitting me. I never had the shot with my daughter and never got sick with her either ..... need a second opinion from you ladies .
