What Causes Soreness In Arm, Blue Spot Near Knot After Drawing Blood?

I had 6 tubes of blood drawn today from my left forearm & about an hour later I noticed my arm was a little sore. I raised my sleeve & there is a 1 inch blue spot with about a half an inch knot in the center. The knot is about an inch above the stick site. Is this normal? She had to use that spot because I am a little dehydrated.
