I wrote a post a couple of months regarding cortisone levels. I now understand what is going on. I have secondary Addison’s disease, I am now depending on hydrocortisone daily. 20mg is my daily dose but this needs adjusting if I’m ill, sick, stress etc. Since being diagnosed I’ve had one adrenal crisis after a sickness bug.i ended up in hospital via a 999 ambulance. I now understand the importance of knowing your own body and how your illness works on your body. Does anyone else in the group have secondary Addison’s?
