Well, that's it. I'm getting old.
I just got a call from the doctor's office. The x-rays show a certain amount of degeneration of the spine due to arthritis, and some little bone spurs.
They're going to send me to physical therapy, and if that makes it worse or doesn't help, then they have the leverage to ask for an MRI to see what's happening in there.
On the up side, the pain IS a little less today.
