I think in your Mom's unique case, you'll have to rely on the information you get from diagnostic testing. Especially, since she can't really relate her symptoms or where she's dealing with pain.
You might want to have an MRE if you feel your Mom is too frail for some of the other test. I wouldn't be afraid of the drugs you're worrying about. There is of course some risk with any medication, but at your Mom's advancing age, you won't have to worry about such long term effects like others do when having to step up to these in a child.
You have to remember that this disease can do an incredible amount of damage and really compromise your Mom's quality of life if not treated properly.
Good Luck with you decision. There's always a second opinion.
