Hi,
The Autonomic nerve controls all the things that you do without thinking to do. More exactly they transmit the message to and from the brain to the respective muscles to do as instructed. Peripheral neuropathy is the touch and skin. Autonomic polyneuroathy is all the nerves. When the nerve endings have a problem the brain is unaware and can respond with incorrect signals ordering up a reactive responce, or it can happen getting through the the particular muscle to react. It can be difficult to diagnose and take some time until someone with prior knowledge gets involved. A lot of it comes under the title of Dysautonomia which is to do with the nerves.

There are many causes of your symptoms so all that can be done is to keep pushing for an answer with the elimination process. Mine took 13 years of negative results and many missdiagnosis.
The autonomic nerve plays havoc with my blood pressure, has totally corrupted my digestive system and can cause all the symptoms of a heart attack. Your heart beat is controlled through the autonomic nerve as is the ability to regulate body temerature.
Most of us get told we have a psychological problem because they can't find anything. Unfortunately Dr's generally all go for the simplest and forget we are not all the same. Medicine is not an exact science.
Eyes that don't react fast enough to changing light, unsteady walking, light headedness, vertigo, BP change when standing, slow reaction to fight or flight are some of the indicators of Autonomic neuropathy. Automatic neuropathy can be caused from heredity, serious disease, sustained high blood pressure, diabetes or naturally. I understand that Long Covid can also leave you with nerve damage (serious disease). I would be asking my Dr to check these things as most Dr's don't think about doing so.
Fingers crossed you are cleared of it.
Cheers
