if my dr is telling me my body is making 0 cortisol what does that mean?  for 6 months my bloodwork comes back that way?  i am freaking out.  does that mean i am on too much steriods?  can it mean i have something else?

does everyone get tested for cushing syndrome along with cah when being diagnosed for the 1st time?  i just feel like i have more symptoms of that then cah.

My dr says my 17-..........  would not have improved with dex if i had cushing but my level was 500 when i 1st went to him last dec.  it went down to 44 with treatment but at last testing 3 weeks ago it is back up to 298.  what could that mean?
