I recently went to get a venipuncture, the woman who did it poked me at least 4 times and was searching for the vein under my skin. my arm is very bruised, and what i am wondering is should i be worried if its hard and hurts when i barely touch it?

Yes: For problems after a blood draw or an IV, one's primary care doctor can examine to see what is going on. In-person examination is needed, so a video consultation would not be too helpful. The doctor wants to fine out if there is inflammation with infection, inflammation without infection, a hematoma, or a chemical reaction (in the case of an IV fluid problem).

Post phlebotomy pain: If a vein is cannulated several times it can lead to bleeding around the vein which can lead to swelling, hardness and tenderness. Unfortunately, this problem can sometimes occur. Try applying moist heat to the area and take ibuprofen and this should resolve over 5 to 7 days.
