I think I had a spider on my right arm and hand! I was sitting in front of my computer watching a video when I felt something on my right wrist and I saw something (big like a 5 cent coin - Canadian - do not know how big they are in the US) black moving so I immediately hit it then got up screaming and jumping! I cannot be certain that it was a spider but I sure am freaked out over this! And to think that I just stopped looking at the computer chair and desk and the television chair with a flashlight before sitting down, here I go doing that again! I looked for about five minutes if not more everywhere with a flashlight and I did not see anything! Okay I just spotted a black insect on the floor but there's no way it was that, it is not a round shape plus it is too small! cry! Oh wow I am itching everywhere and the spot is still burning! crazy!
