I've never had one either, and I'm very nervous. I have to stop my pain meds as of 9:00 PM Monday night and take only one dose of oxcycontin in the AM monday, he wants me off pain meds that day that makes me nervous too. I've stopped taking my Relafen, an anti-inflammatory a few days ago as a prep for disco and I can feel the difference pain wise with that. I was told 3 levels will be checked, 2 are suspicous (herniated, bulge) and one looks good, I won't know which is being tested, but if I have a positive response I will be given a strong pain med injection to relieve the pain, but I wonder, how will I be able to respond to the other levels, unless of course the shot will only last minutes. I'm getting cervical discs checked, how bout you?
