Doctors are stressed, overworked, and only keep up on cutting edge research at yearly conferences and sometimes through the grapevine. Your typical doctor won't know anything about HBOT.

That’s why you should see a good doctor not a typical one. A good doctor would be interested in any research that is well founded despite being non-consensus. That doesn’t mean that they will endorse it. But people like the person I was replying to cuts them out of the process by presuming they already know the right choice for a patient.

Lots of treatments are "potentially beneficial", according to various "authorities", such as grapefruit as a cure for cancer. Going outside the scientific consensus is essentially an argument for alternative medicine.
