For about a year or so I thought that I may have have Addison s...I have a number of symptoms & my cortisol levels are very low. Here are all of my cortisol levels over the last four years... Sep 23, 2014 2.6 ug/dL AM: 10.4-26.4 L Feb 06, 2014 7.5 ug/dL AM: 10.4-26.4 L Jul 12, 2013 2.4 ug/dL AM: 10.4-26.4 L Jul 08, 2013 5.3 ug/dL AM: 10.4-26.4 L Jun 25, 2010 12.0 ug/dL AM: 10.4-26.4 I also have hypothyroidism...I have had this for approx 15 years. My last set of tests results came back normal, but the doctor just had me tested for Thyroid Peroxidase Antibodies & the result came back HIGH - 416.2 IU/mL I also asked to have my aldosterone level checked & it came back at 6.3 ng/dL. I can t seem to get enough sleep, my face has turned bright red & I have noticed a few white spots, my skin is extremely dry...especially on my face & heels. A few weeks ago I also had a CT scan & nothing showed on my adrenals. Does this sound like it could be Addison s or something else?
