I have both on over two and half years quest to find out what is causing strange symptoms. I didn't have insurance because I lost it in my divorce. I been running to every doctor I could and even an Dermatologist for strange skin infections and severe acne. This has been a nightmare. I never heard of Cushing's before this. I am undiagnosed still. I been seeing an Endocrinologist and all cortisol levels,hormones, head CT,abdominal ultrasound, adrenal glands MRI normal. Now unknown mass in my mediastinal area found and going for chest Xray Thursday. I had to beg my primary doctor for that. She thinks it's abnormal fat deposit.? How can this be so hard to diagnose?
