During a blood test, the phlebotomist withdraws blood from a vein in the arm using a needle. Unfortunately, nerves are in close proximity to the major blood vessels in the arm. Sometimes during a blood draw, the needle hits a nerve. This can cause not only pain, but numbness and tingling in the arm or hand. If the phlebotomist hits a large nerve, a person may feel a brief, shock-like pain as the needle nicks the nerve. Fortunately, most venipuncture nerve injuries heal, but it may take weeks or months for the arm discomfort and nerve symptoms to completely go away. In rare cases, the nerve damage can be permanent. Sometimes, swelling that comes from a hematoma causes pain, numbness, and tingling by putting pressure on a nerve.
