Welcome Becky! I'm fairly new to this platform but hope you find some good support here. I have the same, recently diagnosed. I take a small amount of fludocortisone twice a day, prescribed by my nephrologist. Not sure why not the Endo but, it's working for me so far. I was getting acute symptoms of low sodium and with low blood pressure, lots of falls. Haven't fallen since so lots of relief their. Hope you find some solutions that work for you too.
