My husband has also been diagnosed with Addisons disease, and he has the dark red
appearing skin on his neck. It also sometimes appears to have little bumps
, like "chicken skin", but it does not ever itch. When he first saw his Dr., the Dr. said, "Hmm, I think we may need to check you for adrenal insufficiency"; with the Dr. saying that the dark red
or "tan" appearing skin can be a sign/symptom of adrenal insufficiency.
