freaking out about my tb test

I got my tb test done 72 hours ago. I went back 48 hours after the testing to have it read. At the time I had it read it was not at all visible. It had almost completely went away. Except for red dot where the needle went in. I got a flu shot the same day I had it read. Now 24 hours later it is slightly raised and itchy. Was my initial reading wrong? What should I do?
