Today was my third doctor's visit. Not appointment, doctor. But I finally had x-rays taken of my back.
The good news - Normal back spine. Really good apparently for my age and activity level.
Bad news - it's muscle. That means there is little that can be done except for what I am doing, and time - i.e. rest. Boo! I would have loved that magic fix, but it's not the case.
So, I guess it's more PT, keep doing my exercises, and time.
And don't do anything stupid.
