Yes, the 24hr saliva test will test for addisons too. It will give you your cortisol levels for 4 times during a 24 hr day with the normal ranges. Healthy adrenal glands will give a reading at the top of the range in the first morning reading and then slope gradually down to the bottom of the range in the last reading of the evening (10-midnight). The more outside of the range indicates varying degrees of AF. The lab sheet will also explain it briefly with a chart of normal adrenal function range (two lines corresponding with the low and high normal ranges of each time) with your results beside it. If it is WAAAYYY outside the low normal range then you NEED cortisol treatment. If it is WAAAAYYY outside the high normal range then you NEED to lower your cortisol.
When I was at my worst, I was literally loosing my temper continually. My daughter was getting screamed at all the time. My heart would pound afterwards.
I did try isocort before I tested. It was the wrong thing for me and made my high cortisol worse. If you do try isocort, you will probably need more than one a day. Three to four pellets is not unusual. Up to eight a day isn't either. Licorice extract will help too.
Please get your cortisol levels tested. The sooner you know how bad your AF is, the sooner you can start treating it. If you post your results with the ranges, I can get a better idea of where your AF is.
High blood pressure generally indicates high cortisol, but not always....My mother has HBP and she has a combination of low and high cortisol. I have normal BP and I have high cortisol. Low blood pressure generally indicates low cortisol.
You sound like your low cortisol with the tremors, weakness, racing heart, etc. but as I stated in an earlier post, you might have some high periods too. You won't know until you get tested.
