Addison's Disease Support Group
Addison's disease (also known as chronic adrenal insufficiency, or hypocortisolism) is a rare endocrine disorder. It is estimated that it affects about 1 to 2 in 100,000 people. It occurs when the adrenal glands, seated above the kidneys, fail to produce enough of the hormone cortisol and, sometimes, the hormone aldosterone
As for going into crisis; you have some of the symptoms but the main ones I have always noticed before a crisis are; extreme fatigue, lightheadedness, nausea/vomitting and diarrhea. I would definitely follow up with a different endo and request an adrenal stim test. Also when you see your primary care doctor get a B12 blood test. Some of your symptoms can relate to low B12 levels. If your B12 levels are low, B12 shots are an easy fix and can make a huge difference.
Good luck in your health search.
