Looking for some advice.. I had my blood drawn a bit over a week ago for a routine exam. At the time it seemed alright.. I've been stuck with a lot of needles in my time and i'm quite used to them.

However, that started to change. By the second and third day after, when the puncture spot is usually completely healed for me, it wasn't. On top of that, my arm was still very sore and slightly blue as if it was bruised around the needle area. I wrote it off as the nurse hitting a bad spot.

After 9 days I can still slightly see the spot where the needle was inserted. There's now about a 3 inch long area on my arm near the needle spot that has turned a shade of yellow. A bruise still i'm thinking, but now i'm not so sure... My arm is still as sore as the day the blood was drawn if not more. It's tender around a 6-inch long area from elbow toward hand, even though i've been "babying" it since the test.

Am I making something out of nothing or could this be something serious? Infection? (nurse used alcohol first and followed normal procedure) could she have done some damage to the arm when inserting the needle? I'm concerned about this, but I don't want to go to my doctor and end up looking like an fool if he tells me it's just a bruise.
