You shoudl consult with an attorney. On the face of it, you may have two distinct claims here, as you have intuited:* Commerical use of your likeness without your permission* Invasion of privacy (at least if the facts are such that a reasonable person would not want them to be divulged)You may be able to sue the chiropractor for damages. You might also be able to get a court order stopping them from doing this.However, on a more practical basis, if they have done this before, so this is the second time, you should probably take your custom elsewhere; they do not appear to be  very respectfual of their patients' rights.
