I just gave blood and problems with both arms. The first attempt made was in my left arm. While the needle was being inserted it was very painful and it felt like numerous bees stinging from the stick area all the way down to my wrist. The nurse pulled the needle out and placed an ice pack on my arm. I experienced numbness immediately upon the needle being inserted and now 3 hours later my arm is still numb. Will that go away? The nurse stated she probably stuck my nerve by accident. Then she tried the right arm and it too was extremely painful while the needle was being inserted in my arm! And,it took forever to collect the blood. They finally loosened the band around my around and tried to re-adjust the needle which again was very painful. My hand and wrist had turned blue and was numb. But this improved once they loosened the band and adjusted the needle. The right arm is still painful 3 hours later in the area where the needle was inserted. Do I have anything to worry about, because it felt like both veins very pricked.
