Thank you all so much.....I m overwhelmed by all the replies.......but I will admit I am still scared as I had no less then 25 atempts to have an IV started before they put in the cental line (which 2 clumsy nurses ripped out as they were flipping me all around and i was ordered to lie flat and still) and I hate needles....and no way can I tolerate this test without my pain meds and Lyrica so I just don't know. My numbness is scattered in my feet and legs...toes are complete and the total loss of feelings the many times I fell. I may just ask her to postpone it since it is so soon after my horrible experience at that hosp......I was treated so badly and suffered so much pain that I wanted to die! I was a nurse before the endless pain made me quit so I do know how I should be treated and I am very paranoid and scared for now.
