After flu shot symptoms (ASAP please, may be important)
Today, my sister had her flu vaccination around 4:30pm. I know where the needle breaks the skin is usually red and somewhat sore, but it is slightly swollen, the redness is about double the area of what I found is normal, it's extremely sore, and her arm feels "tingly". I can't find anything online that is saying this is normal or not, so please share your personal findings. should I take her to the doctor??
