Cathy, are you exhibiting many of the symtoms of automic neruopathy? It can vary widely in the systems that is does effect, and also the severity.....

Essentially, it is caused by damage to the nerves that you cant control but you need to survive - heart rate, blood pressure, digestion, perspiration, etc. and can range from very mild end results such as some dizziness which you can adjust to (the result of an improper drop in blood pressure - your body doesnt adjust to "altitude" changes), to cardiac issues, gi issues resulting in gastroparesis (paralyzed stomach and intestines so your food does not digest), heat intolerance, UTI problems, etc..... essentially your autonomic nervous system is not correctly comunicating with your brain.

I have both small and large fiber neruopathy - and the autonomic portion is severe... usually and as in my case - the symtoms are managed by spcialists who treat the organs affected.... a cardiologist if your heart is misbehaving, a gastroenterologist to help to be able to continue to eat, urologists, etc... meds help some symtoms, change of diet, change of exercise habits, etc.... its important to find specilaists who understand that neruopathy is the underlying cause of any organs needing special attention and who hepefully work closely with your neurologist (who will diagnsos you but doesnt do the hands on treatments for most of the end results here)

Hoping you can get accurate assessment of what you may be dealing with - and proper treatments..... Just hang in there....
