Educate phlebotomists
I wish I could show pictures. I had blood drawn by one girl and it hurt! She was careless and left a huge lump that bruised, making me look like a drug user. I went back a couple days later and requested the one I knew was an excellent phlebotomist. I barely felt anything and she left only the needle mark. No bruising. There is a special way to take blood and they all need to learn to pull the skin tight before sticking the needle in. Please educate everyone who does this! Simple technique.
