Nerve damage from getting blood drawn

I had bllod drawn last week for a basic test. They took one quick vile of blood and sent me on my way. The problem is a week later, the back of my hand is numb and it feels like I'm gettig shocked everytime I bend of straighted my arm. It has been exactly one week and everyday it gets a little bit worse. If I touch immediatly to the outside or my center veign it starts sending shocks down the back of my arm. I have read about a few other incidents like this one but the difference is I had no bruising or excessive bleeding. Besides feeling like she jammed a 6 inch long needle down my arm when I was stabbed nothing has been out of the ordinary. My issue is unfortunately come the first I am no longer covered under my parents insurance. If this needs furthur medical attention will the company who employees the phlobotomist responsible? Any information on what to do next would be helpful. Being able to fully use both arms with no issues is extremely important to my career.
