I'm going to have a spinal tap done soon and i'm very scared of needles. I've been putting it off for a long time but i recently had to go to the ER with my arm getting weak and a unexpected bruise on my spine and headaches. So they really want me to get it done to figure out whats been going on. I'm really scared i'm only 19 and i don't do good with pain. I'm worried that i will jerk when he gets the needle near me and i'm wondering if anyone has moved during this procedure and did it make things worse?
