The exercises are starting to help a little. I did learn lumbar neutral stance and walking with Chi Running not too long ago so I'm working on that again. We did talk about cause at the last PT visit. I have a full-time office job so I spend a lot of time at a desk. Also, back in February I got a new dog and have been walking her every day. Her pace is a very fast walk/not quite a run pace for me, so this means stretching out my stride more than I was used to. I'd hoped a longer stride would help with my running, but my PT agreed that this along with a lot of sitting at work might be what caused the current problems. So the walks are now at a slow pace to the park and then the dog can run on a retractable leash. PT is also having me get up and stretch several times throughout the day, plus continue with the other exercises.

Back to the doctor tomorrow - see what he says.
