Got bit by some thing! :( (*PICTURE*)

So I was outside and something felt like it stabbed me and I picked something off of me and my first reaction was to pull it off and throw it. I probably should have looked at it first to see what it was but I was in too much pain. I took a pic of the bite spot and it has been hurting so bad. My doctor won't let me come in he just said probably a bee or spider bite and that was it. I have a picture below sorry bought the hairy leg in advance.
