Does this look infected?? It was tiny it seems like its gotten bigger in last few days?

Yes

Yea it kinda does is it warm to the touch?

Definitely. It's red around the injury. Means infection. And it's alot of red. Neosporin could help with that with a band aid. And cleaning it with peroxide before all that

Yes. That does not look good. I react badly to insect bites. That is exactly what they looked like when I was little.
