I Had Blood Drawn Today. It Was In A Small

I had blood drawn today. It was in a small vein near my wrist and after 2 vials she couldnt get anymore blood. Spot is swollen and now the side of my thumb is becoming swollen bruised and painful and my upper arm is sore. Should i be worried. I am 65 years old with what they call rolling veins. She did not draw blood on my thumb.
