Better physical therapists through bar hopping

Yesterday, at the bar, I was talking to a girl who was a physical therapist. Surprisingly, when I described my injury, she was familiar with it. She even knew exercises I should be doing to help it heal. Of course a bar isn’t the optimal location to show therapeutic muscle stretches. She suggested I show up at her yoga class the next day.
So I did just that this afternoon. A yoga class. I wasn’t at my most flexible, I had just finished running 17km that morning. Still, it was a nice bit of stretching. I’m just worried about the aches and pains that I expect to hit me. That’s why I haven’t been to a yoga class for several years: The agony it caused when I also did running made it not worth the trouble.
But now I know the exercises I need to do. Which makes me ticked off at the physical therapist I was using. She treated me like a new discovery and didn’t really know what needed to be done.
