Weekly blood test :(?

I am sure that your doctor wouldn't send you for blood tests if they weren't necessary. Do you make sure you drink lots of water before you have blood taken? I have bad veins now due to chemotherapy and I try to always drink lots of water up until I have the test and a heat pad on the part of the arm where they are going to take the blood can help too. Most places are pretty good at getting blood without too much pain, maybe you could go somewhere else to get it done if you don't like the people that do it there.
