Hi, last week friday I had a nurse draw a small blood sample from my left arm. when she initially went in with the needle, i felt a shock go through my arm up to my thumb area. Two days after i started feeling a numb feeling and a slight shock to the thumb area when i flex my arm in. I went back to the doctor who was overseeing the blood draws and told him about my problem. He did a simple evaluation of applying pressure to the area and have me move my hands and fingers to let him know when I feel the shock. After the evaluation, he didnt mention to me if it was serious or not but just told me to call back after 5 daysto update him on my arm.
Should I be worried? or is this a pain/sensation that would go away with time?
