Hello.. I Got Blood Drawn From My Arm On Monday.

Hello.. I got blood drawn from my arm on Monday. When the tech placed the needle in my arm I felt a tingle shoot straight down my arm to the tip of my thumb. Ever since that day every time I stretch my arm I feel the tingling & also a pulling pain from my mid arm to thumb. When I swing my arm I have the same sensation. I wanted to know what could of caused this & what should I do?
Thank you
