It's a dysregulation of the ANS/sympathetic nervous system which is likely caused by auto antibodies - so it's very much physiological and outside the expertise of a psychiatrist.
So, any good doctor will try to heal your symptoms regardless of the cause. The only difference when they think it’s psychosomatic is that they’ll also try to treat your stress.
The symptoms exist, they are originating due to thoughts/beliefs in the mind.
Unfortunately, when there isn't an obvious matching hole they tend to stuff them in wrong holes (there are conditions for which getting the right diagnosis often takes years), or when they don't see any appropriate hole they stuff them in the "crazy" hole. And the doctors are very reluctant to take a pigeon out of a wrong hole, especially if it's the crazy hole.
I recall a thread on here from some years back, diagnosis: anorexia. Real diagnosis: partial gastroparesis. She didn't want to eat because her body wasn't pushing the food on down the system properly and eating was very unpleasant!
did you mean to say psychologist? In the US at least, psychiatry is a medical practice area. Writing Rx scrips requires pharmacological training, so you need to hold an MD amd pass medical boards etc. Not sure if DO route is even an option.
Psychology otoh can be practixed with a Psy.D (clinical focus) or Ph.D (research focus) no MD, residency involved.
I called my doctor's office to schedule an appointment and when the receptionist asked what the appointment was for, I simply said "brain fog". I had no other way to describe it.
It was intense and disturbing. I often couldn't put cohererent thoughts together, I was constantly forgetting what I was doing, forgetting where I had just put something.
Over the coming weeks it slowly receded, but there's no doubt it is real.
I've had people dismiss it as "it's all in your mind". They're right on some level ... it was in my mind. But it was very real, and I have no doubt it was SARS-CoV-2 related due to the timing and sheer intensity of it.
