I'm not sure why they'd do one side at a time, either, but the way I
understand it is that they're going to do the right side first and then
I have to keep a "pain diary" for a week. If there's any improvement
in the pain, then they'll do the left side. What's really confusing me
is why they would start with the right side, when it's the left side I'm
having trouble with the most.
