Zophie: You will be able to see the x-ray on your first appointment if and how your atlas is misaligned. It was a trip to see mine! The way it was misaligned was exactly the way the rest of my body followed suit and was also misaligned. I can't say enough good things about AO. Make sure you watch Montel Williams' testimonial at that link about his nerve pain and what happened after just one adjustment. The person who told me all about this said that those kind of responses are not uncommon. I didn't want to get my hopes up too much, but then I had a massive response to my first treatment.
To the OP: Is the nature of your injury skeletal or soft tissue, or both, or do you know? That would determine which course to take. In my case, it was both.
