I too have been diagnosed with adrenal insufficiency. I’m at 5.5 mg; I was hoping to tough it out until my adrenal glands start working again. I have abdominal pain and body aches some days. Most days I just feel weak and tired, with bouts of nausea. I see my rheumatologist next week (she diagnosed me a month ago). My plan is to ask for another cortisol test; then in a few months, another ACTH test. If both aware improving, I’ll hang in there. If not, then I’ll ask for a referral to an endocrinologist. My understanding is the treatment for adrenal insufficiency is more prednisone or hydrocortisone - but I’d like to get my OWN adrenal function back. In the meantime, I carry 10mg prednisone in my purse in case of adrenal crisis; and I wear a medical alert bracelet.
