I noticed what looked like one red bump on my left arm, and I scratched it and the rash looking area seemed to spread. I had been bitten by mosquitoes in other places so I figured this was just a
mosquito bite. However, while most of the mosquito bites ( face, back, neck) went away like nothing happened, my arm bite, turned into a purple bruise. Then I found that there were three others on my arm like it, each with a small but noticeable darker dot in the center.
