I received a flu shot at 7pm at Costco Tuesday night, Wednesday morning at 4am I woke up to extremely itchy, red hot palms. The injection site is sore but not red or swollen. Because I had to go to work I took an advil
Cold & Sinus which took the edge off the itching
and running my hands under cold water help
ed a bit. By Wednesday night my palms were bright red, hot, swollen, so itchy and my finger tips were turning purple. I took a couple Benadryl so I could drive home from work.
