Possibly: Unfortunately, bruising after phlebotomy is a common side effect especially if you are on blood thinners. If the bruising continues to spread, becomes excessively painful, swells, becomes red & hot, a visit to your doctor is indicated.

No: Unless the area of bruising continues to expand, you don't need to worry. It's not unusual for there to be some bruising after having blood drawn, particularly if it was a difficult stick. It will heal just like any other bruise.

No: Just blood under the skin. It will go away.

Depends: After a blood draw, if there is slight bleeding underneath the skin, this creates the bruise. If enough pressure is placed after a blood draw, there should not be much bruising. If it is a small bruise, there should be no reason for alarm. It usually resolves within a week. If the bruise is large (extends farther from the are of the blood draw) and causes pain, seek medical attention.
