What a bummer to have this problem and not know what it is or how to treat it.  The thing that I think all 3 of your possible causes have in common is the effect they have on your Central Nervous System (CNS).  Recently I have been reading about a promising treatment for long COVID that involves transcutaneous (non-invasive, through the skin) Vagus nerve stimulation.  The vagus nerve is part of the autonomic nervous system (ANS) that ramps up the parasympathetic side of the ANS.  Small electro-stimulus devices are on the market that specifically target the Vagus nerve which is close to the skin surface in the neck and ear.  They boost the activity of the nerve which in turn ramps up the parasympathetic system and turns down the sympathetic.  You should google this as there is a ton of information and studies on this subject.  My reading has caused me to wonder if this same treatment could help with OTS.

I’m sure by now you are getting pretty desperate for help. I encourage you to investigate this and make your own decision.  There are a few devices that are FDA-approved for this treatment and are being used for long COVID in many major institutions like Harvard, Mayo etc
