I had back problems, too. It was work related (too much sitting in front of the computer) and affected the muscles in my upper body, shoulders and neck. I tried Yoga back then, and Pilates. Pilates was actually better. Also hot showers and sauna helped wonders. Now I work out 3 - 4 times a week and if I don't I do at least some light stretching in the mornings. No problems since.
This may be unrelated to what you have. So I recommend you go to a doctor first to make sure there's no serious condition.
