I fell down some stairs at the age of 10 and for a couple of years I went undiagnosed. It transpired that my coccyx had moved and fused incorrectly over time.
It took me several years to find a doctor willing to manipulate my coccyx back into place. I met Sanne (see Doctors and specialists in Denmark) at 16. After 6 years of intense back pain, I saw her for 3 hours during which she undid all of the compensation knots and finally manipulated my coccyx back into place. Having been restricted to 6 hours of lying down every night since the age of 10, I slept for 19 hours straight following the treatment.
Sanne is a fantastic doctor.
Note from Jon Miles:
I emailed more than a year after this story was posted, to ask for an update, as the long-term outcome of treatment is of great interest. In this case I did not get a reply.
