I think something is wrong with my tongue, please answer!?

A few days ago I went to Subway and I got a sandwich. I came home and started to eat it, I got halfway through the 6 inch sub and all of a sudden I tasted something that was just like *spicy*, thats the best way to describe it. I felt a sensation in my mouth that I never felt before. I quickly spit it out and what came out? A bug! It was still alive. It walked around on my plate for a few seconds and then promptly dropped dead. I determined that it was a stink bug. I quickly took my sandwich and the bug back to Subway, and well lets just say I am still dealing with them. I thought that I was ok, but a couple of days ago I started to feel a soreness on my tongue in the same area that I felt/tasted the *spicyness* and also the side of my mouth on that side was kind of swole up on the inside. It was so swole up that it reached my teeth and I was biting down on the side of mouth for, well, even now I am putting cotton in my mouth to keep from biting myself. I am not in a position to go to the doctor right now, but I was just wondering what kind of things could I have gotten from the bug, if indeed I did get something.
