Ok, this is most probably "an old fish" for most of you, but I hope I can profit from your knowledge and personal experience. Due to POTS and due to low cortisol it was suggested (by two or three doctors) I'd take hydrocortisone, 10-20mg per day. I remember longterm intake of (hydro-)cortisone can be problematic in ME. Is that correct? Are there experiences? Do you have suggestions? I would have started with 3mg in the morning. I wouldn't take 10mg. I will be checked for Osteoroposis next week. In Germany, Calcium isn't prescribed with cortisone. I remember Calcium needs to be taken, too. How much? Already lots of thanks for a reply!
