Okay, I consider myself a "tough old bird", but had to get a blood draw for cholesterol check. I stuck out my arm, held it still, I really don't get too shook up about giving blood, she got her sample and said oh, you may get a bruise.....I was thinking about a nickel size bruise might show up, but this bruise is a whopper....It is about the size of a baseball and starts at the crease of my elbow(where she "stuck" me) and goes practically all the way around to my elbow.... I have never had this happen before and the funny thing was she was showing a "trainee" how to take blood. I was worried the trainee was going to stick me, but the experienced nurse did it...... Should I be worried about the bruising or is this pretty common?????
