The exercises I got from another fill-in doctor in March helped a lot for most of my back, but the lowest part was still sore. I've been working with a new set of moves for almost a month now, and results are slow to come. But last night I got in bed and wasn't immediately in pain for the first time since back in March. Of course I was still sore throughout the night and all through the morning, but getting in bed and going to sleep pain-free was a wonderful feeling.
I really hate doing two sessions a day on non-walk days and one on days I do walk, but last night was definitely good motivation to keep going. Though it's hard to say for sure if it's all due to the PT. I added a wedge to my bed to use while sleeping on my side and had been on it a couple of nights, so that could be a factor. Nothing to do but stay the course.
