I had my blood drawn almost 2 weeks ago and i still have a bruise and it is still very sore. there is a purple spot on the bruise too. is this normal?

Vein trauma: Venapuncture normally doesn't leave a tender area that lasts two weeks unless the vein became inflamed(superficial phlebitis) or a blood clot under the skin developed. If warm packs don't improve the situation and there is a persistent tender clot, it may have to be removed by a small incision by a general or vascular surgeon. Discus this with your physician.
