After waiting 2 months, and my doctor's office pulling the lab reports and faxing them to the endocrinologist with a note to call me.... Negative for Cushing's. Back to square one. I told my doctor's office that I want to go back to a neurologist to check for neuromuscular disorders because of the profound muscle weakness and muscle fatigue. But, I think I'm done searching for answers. I'm too tired and drained to keep doing this.
