OK Doc. I will try and do this. I have the printed directions out. I really did dig awhile for research. I know that each verterbre is investigated with a needle and scope, so he can see on a screen what is going on. This dear woman has trouble in alot of different areas in her back, and that is what concerns me, that and the maybe lack of insurance coverage. I will get my son over to me to help with posting as well for the public. That is a good idea, since this test has not been mentioned much on our NT. Have a good day doc. I will see about doing this. ginnie
