I think you first need to relax about the test. It didn't hurt that much. I'm not saying that I didn't feel it, but I have had worse test. If you relax your muscles will be loose and not all tightened up. You'll be better off relaxed than all tense and in muscle spasms. Do you take anything for anxiety? I take Ativan. It helps with my chronic pain and relaxes me to the point that I can fall asleep. Think about something else when the test is being done. You'll do just fine. Good luck and post how you did. Hopefully there are no tears and it will feel just like pressure in your back.
