Which is more painful?

I did a blood test for blood glucose today. Have to fast the night before and blood test was done in the morning. 1st they will let u drink a bottle have very sweet drink then after that they will draw blood 3 times. Each time is half hour gap . I also did vaccine on the same day. So my left elbow right forearm elbow both was use to draw blood . Vaccine was administered at Upper arm. Overall bearable . A lot of it depends on individual and also the skill of the nurse performing it.
