I have read on a site that they will take my medical history and if there is a history of any autoimmune illness like RA, MS, or autoimmune thyroid they will not proceed anyway.

Since I have clinical Graves Disease I would be knocked back and they would refuse to inject me most likely. If they are truly diligent to ask me in the first place.

At this stage I am going to give this procedure a miss.

Thank you for feedback/opinions.
