Getting blood drawn is my absolute least favorite thing in the world. I refuse to get it taken out of my arm, I always have it out of my hand (the veins in my arm are very hard to find, and i had a few too many similar experiences to the one you had today).
I just scheduled a surgery for the end of August, and was informed that I need to get labwork done for it. I am NOT happy haha!
Feel better soon.

hopefully the bruising will go down. Next time youre there shank them with the needle.
