So here is what happened. I went to give plasma about a week ago and they stuck my left arm, but oxygen hit my blood so it was too thick. So they stuck my right arm and it was going good. Then during the first return of blood, they realized they had scratched my vein and so they had to infiltrate me (give all my blood back) and so it formed a lump of blood...and this bruise is the end result. Don't worry Ma and Pa...it's not as bad as it looks.
