Anyone have any experience of this?
I have a diagnosis of POTS and small fiber peripheral neuropathy however I have some symptoms that don't fit into these conditions but do with secondary adrenal insufficiency.
I asked my dr for cortisol test today and said he didn't think I had it but agreed to blood test.
For info I have low b12, vit D and ferritin. Serum tsh is 1.4 in range of 0.3 to 5. And all sodium, calcium and potassium in range. Thanks
