Today I was sitting on my front porch, and a small, brown bug landed on my arm. I went to brush him away, but he flew off before I could. I didn't feel him sting me, but about 1 minute later, I began to feel a burning sensation where he had been sitting. I live in Georgia. The bug was about the size of a mosquito, brown, an insect. There is no swelling or mark where the burning sensation took place.

Now I feel a little nauseated and tired. Are these related to the bug?

My mom has often told me about sweat bees, and my symptoms sound like what she describes when one receives a bite.
