Sandy, several years when my PCP wanted a MRI, he said he would send me to Traverse City because they have an open machine and if I'd have someone drive me, he'd give me something that would make me not care where I was. We probably have that machine now as we have a new multi million dollar imaging center. There's no sense arguing now. Even if I don't do anything, I need to know what's going on.
BTW, have you ckecked your local PBS station for 'Sit and Be Fit'. She uses a ball (dollar store), weights, a towel and bands on alternate days. The first part is seated and on the second, you can sit or stand.
