I had blood drawn a week ago, they took 10 viles. I was laying down with my arm down. Halfway thru the draw, which was at the inner elbow, I had a sharp pain down in my wrist. The nurse said I had started bending my arm, which I didn't notice. I help my arm down straight and after 30-40 seconds, it eased. Today, 5 days later, I am getting a strange feeling in the same spot in my wrist, also a little discoloration. Is this normal?
