Had a really good physiotherapy session yesterday morning, and a pretty good day over all; a big difference in comparison to the day before.
I've got a couple of stretching routines added to my exercises. Maybe they helped? Or maybe I'm just being more aware of my posture sitting at my desk. Regardless, I felt pretty good and I had a good sleep last night, without waking up every hour or two. It'll be a week until my next appointment, so it'll be interesting to see how just doing my exercises will work out.
I'm still fighting the urge to try cycling.
