I am diagnosed with Auto-immune Addison's disease.
WHat I would like you to do is take your blood pressure sitting and then standing..give me both numbers.
Plus while standing take your pulse (heart rate) if heart rate is high it can mean you are low on sodium.
I suffer low sodium issues ( low aldesterone).
I understand about ENdo's oboy...I went through hell before being diagnosed.
You may want to get a salvia test...this will show your cortisol level throughout the day..You have to order it over the internet.
