Hi, my cortisol is a bit higher than last time it was tested a year ago and outside the range. I am not diagnosed with hypothyroid or hyperthyroid though I am diagnosed with Fibromyalgia. All my other bloods have improved in the right direction eg Vit D, Iron, Vit B12, prolactin. My GP did say to get it retested in a 3 months time. I have read about Cushing's Disease but just wonder what else could be causing high cortisol. My blood pressure is fine. I am very tired. I don't feel hyper like I used to but lacking in energy.
