I've been in the program for one month now. I've seen great strides (walking without cane or brace, bending down, etc.). Today I spoke to a group about the positive results I've been having. As I exchanged hand shakes & hugs, I felt the familiar spasm along my lower back! Has anyone else encountered this? It's as if I'm afraid that my progress is a 'house of cards'. I'm also experiencing more sleep interruptions. I've been journaling and trying to decode this new challenge.
