The pituitary gland is another source of making adrenal hormone. Your nephrologist might not pick this up. You know the little ditty "your knee bone is connected to the ankle bone . . . " but what about the other stuff in between that needs looking at. Don't need to be crass, but have been in that situation. That is why everyone's comments are truly appreciated. We are all working together trying to solve our health problems. I thank all of you.
