..I had a shot in my neck in 2017 and it's still holding. Mz ribit has had a dozen or so and they last about six months. They could do surgery but they / she don't want it. She remembers her knee surgery and is gunshy.

Your shots lasted 3 years? Wow, I was never that lucky.
I can't blame mz ribit, not just for avoiding the shots, but avoiding surgery, too.
After surgery, we get to have REHAB. ohgod
