Well, the issue will be whether you agreed to be video taped. If nothing in the documents you signed indicated you may be videotaped, you have a strong lawsuit against the doctor. You may wish to take all of the documentation you have, a copy of the video and proof on how you know this is you and take it to a medical malpractice attorney. See if there is anything you can do to sue or at least issue a cease and desist to have him take the video off of the internet.
