Cushing's: There are several ways to screen for Cushings: 24 hr urine cortisol, overnight dex suppression, and midnight salivary cortisol. All would be altered if you took a steroid suppository. All need confirmation from other tests. Intermittant steroid use can cause symptoms of Cushing's, but no reason to think there is a tumor if you are taking steroids. You may need to see an Endocrinologist.
