I came in for treatment with Michael Durtnall and his team when my coccyx had suddenly flared up without warning (see Doctors and specialists in the UK, London).
I've seen Karolina, Michael and Marek. Within just a few sessions I was already on the mend, and the pain has almost subsided completely. Very impressive.
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.
