Common: Needle entry for blood drawing depends upon the surrounding tissue to seal off the blood flow so it only goes into the needle. Unfortunately this is imperfect and frequently there will be leakage into the adjacent tissue. This is usually a tiny amount, and harmless although it might leave a short term tissue stain until your body absorbs the blood.
