My boyfriend went after a really bad snowboarding accident, His upper back is better, and his knees use to hurt from work but now they don't.
Plus, My friend she went and her chiropracter knew she had a murmer without telling him. And that her pelvic bone was pionting to forward which caused her lower back pain. She feels much better. And I swear she's gotten taller. (She sits up much more straighter)
I think its good to go.
