I had a blood draw yesterday, and the nurse stuck the needle into my nerve. I felt a horrible pain down my arm and into my hand. she did not take the needle out right away, as she had managed to hit the vein. I went to the urgent care in the afternoon, complaining of nerve pain all up and down my arm. Dr. prescribed hydrocodone. Today, my hand keeps having those little zings of nerve pain and my arm is very sore. How long will this last? and is there anything that will help in the meantime?
