TB test...kinda paranoid ?!?!

I had to get a TB test yesterday bc I volunteer at a hospital. It looked completely fine yesterday night, maybe a tiny tiny bruise that was 2x the size of the needle injection which isn't big at all. 
This morning I woke up & it was red & puffy. I'm pretty sure I don't have TB, but I'm afraid if I go back tomorrow & it still looks like this they'll make me do more tests thinking I do. 
I know they'll do a chest x ray if undecided, but I've heard other things too. Also, the past 2 or 3 times I've gotten them, within the past 4 years, they've been red or puffy. One time it was bc the nurse did it too rough, but they said it was negative. I did however put numbing cream on my forearm bc I'm afraid of needles & taking the pain away helps (I did this for a flu shot & worked perfectly with no reaction). 
My mom partially believes it could be from putting that on, but I don't know what to expect when I go get it checked tomorrow?   I absolutely do not want to get another one & I do not want to get more tests (besides the chest X-ray).
