We have recently taken my son to the doctor for exhaustion, depression, moodiness, odd stretch marks, rapid weight gain, muscle aches, etc. She sent him for blood work. She checked his thyroid, for anemia, and his cortisol levels. She said that she felt sure that it was his cortisol levels because of the rapid weight gain, his round face, and the fatty pocket on his collar bone. On the way home my son mentioned that he thought that it could be Cushing's Syndrome. He had seen it on House. I had never heard of it before. He showed me the info on the web when we got home. It seems to describe all his symptoms perfectly. He has gone from losing weight and running every night to barely being able to walk with the family. So the blood work came back and his cortisol levels were normal. I expected that if it were cushings that they would be off. We go back to the Dr. on the 22nd, and I want to know if I should push for further testing. Please give me some advice.
