Yeah when you have knots in a muscle group, you know it. I'm glad you found a resolution. PTs are worth their weight in platinum.

I was surprised at the diagnosis from the MRI - tight lower back muscles? I'm not even sure I know how a radiologist sees that, but apparently that was true because the stretching I described fixed the cramping.

Good for you for working with a PT. I have a personal trainer at the gym, I see him for 45 minutes twice a week. I've had plenty of ailments and surgeries since starting to work with him, and he always has ways to work with or around a problem area.

And he has shown me so many different ways to perform an exercise to benefit a particular part of my body. I would never figure out these things myself. They are a bit on the expensive side, but it's some of the best money my wife and I spend. And it's for the good of our health, which has no price.
