I had the flu shot yesterday and I remember it being itchy. I’ve been experiencing other health issues and symptoms for the past month. My wbc is at 15.3 still unknown as of last week.. and still the same after it was retested as of yesterday. So I noticed the spot on my arm a couple of hours ago from the flu shot and it doesn’t look normal. The redness is about 5 inches long. Is this normal? And also could it be from my wbc already being elevated
