Agreed. I've always stated that I've never been "diagnosed" with AF. Because, well the medical community doesn't recognize it. And I may very well not have AF anyway, but I know that something definitely went wrong and, from what I remember, it switched on over night.
I often ponder how people are coming to the AF diagnosis. I think a lot have read the symptoms and after many years with little to no help from doctors, came to their own conclusions.
Others have opted for tests like salivary testing. This may be an indicator of your hormonal levels, but how does one know that its the adrenals that are responsible for the sub-optimal/high levels. For all they know it could be a pituitary tumor causing high cortisol levels or maybe hypothalamus inflammation, etc.
