So it turns out my back problems from the past 10 years is a case of Scoliosis.
Started seeing the chiropractor this week, and he should have the x-rays by either tomorrow or Friday.
Scoliosis is a bitch. They wouldn't let me join the Bundeswehr (=German military) because I had/have a minor case. Not that I wanted to join... so yay for Scoliosis.
Physiotherapy helps a lot though. My spine went back from a slight S-shape to almost normal.
