I just re-read the radiologists report, and the atrophy is only on one side, and it is mild.

I think I am going ahead with the first procedure tomorrow, since it did seem to help when I had it done (at the same place) 5 years ago. I did have a nice talk with the radiologist about his outcomes, and only one patient ever felt worse after the procedure, and most felt better.

I wish I had a crystal ball!
