Hi, I m a 21 year old female with Cyclic Cushings. My Endoxrinologist said it could take up to 10 years to detect. I ve had an MRI scan of my brain to detect a pituitary tumour, but the results came back negative. While my 24hour urine samples do not show high cortisol levels at all, my physical symptoms are severe, and I m a trainee counsellor and nurse, What would be the next step of action when all I do is waste my time getting negatives? Would it be profitable to have an MRI done for my adrenal glands? And if, after all that, I still show up clear but am obviously symptomatic, what treatment could I get?
