Last Thursday I had labs drawn. The tech prepped me in an area that never has been drawn. I have small veins that roll. It started okay but then the blood stop flowing so for the next 2 minutes she dug in my arm with the needle (they have to use butterfly). I have a bruise the size of a half dollar. I had a knot the size of a dime for four days. Now I cannot lift anything with any weight (not even a gallon of milk). The tech did this in my right arm and I am right handed. How long is this going to last? What can I do to make it heal faster?
