Last weekend, I noticed a raised white spot on my arm and paid no mind to it. The next time I looked at it, which was the next day, it had turned pink and I assumed that I got bit by a mosquito or a gnat and again didn’t pay much attention to it. A few days later and I noticed that it had shrunk.
Here is a picture of it as it is now, with me circling the area in question. I know the pic isn’t the best quality, but it is what I can manage. Now, I’m slightly concerned about it because, now that I inspect it, there are two marks that I assume were the bite marks. I’m just wondering if it was a mosquito/gnat, a spider, or possibly something else.
