blood

I hate having to have my blood checked. I get checked every once in a while for cholesterol, high blood pressure and diabetes. But I hate it. Because they can not find a blood vessel in my arm. It takes for ever to find one. Last time after 10 minutes they found one. They stuck the needle in. And barely any blood was coming out. They wondered if i had fasted the 12 hours. Of course I fasted the 12 hours. Did I drink water. Yeah I drank water. Finally after filling 4 tubes full of blood. They took out the noodle. It always worries me that its going to leave a mark. Like I am some heroin addict. That I will have to cover up for a week my arm. So the needle bruise will not show. Some times they do a good job and no needle marks show.
