Just diagnosed with secondary

Hi all:
I am a 46 year old female just diagnosed with secondary Addison’s. Hospitalized twice for a week each over three weeks and thank goodness the doctor found it. I am not feeling well - had knee surgery a week ago and that brought on another bout. Does anyone have suggestions re: what I can do to increase my health? I am taking 10 mg. hydrocortisone in the am and 5 in the pm but have been doubling since the surgery. Wishing you all good health.
