From the info you have given us so far, I'm not sure how helpful your post is to people with CRPS.

You say that you don't have a diagnosis of CRPS. That is the particular condition that people on this board are dealing with and is what they would be presenting with when they are discussing any potential treatment with any doctor. I am sure you are well versed in managing your own condition - many people who post here are very clued up on CRPS and its pretty normal for us to routinely have to tell even specialists about our condition and the potential treatments out there.

For a doctor to perform a non-approved high-risk medical procedure involving a medically induced coma on a CRPS patient on the pretext of dealing with some other medical condition would probably be at best regarded as unethical. I am guessing that was what your "wink, wink" reference meant? I'm not sure how placing a CRPS patient in a coma using a different anaesthetic drug and then infusing ketamine would get a doctor round the FDA or a hospital ethics committee. There would need to be a justifiable medical reason for placing a patient into a coma and even severe CRPS definitely wouldn't be a justification.

Are you actually sure you you were actually placed in a coma? It may have been deep sedation but if you were truly placed in a medically induced coma, you would have to have been incubated and ventilated because the body is physically unable to perform this function in an induced coma state. All of the body's needs have to met artificially. I ask because the way you described the process and the breathing intervention suggests deep sedation and not a coma.

It would be interesting for you to come back provide more information. I guess that since the particular doctor who provided this procedure has an email address that is publicly available online, people could contact him direct if you don't come back and post more information.
