I have no idea what is going on....

Here is the whole story -

About a month ago I was getting blood drawn and the nurse hit a nerve, and my left arm was numb for 3 days and still has mild numbness in my pink and ring finger.

However, the past 10 days I have felt a similar numbness/tingling sensation in my feet and hands. It seems to be very position dependent - as in if i sit for too long my feet get it, if my hands are propped up at all my hands get it, if i lie down on my back with my legs stretched out i get it. I have also been having intermittent joint pain in my knuckles, wrists, and knees, as well as chest wall pain and back pain in my shoulder blade area. I have also felt a bit queasy at night...

I went to the doctor about it and their only response was, "if it doens't go away in a couple more weeks come back".

I assume the numbness is some type of neuropathy, does anyone have or know of similar symptoms that might be what is going on?
