Hi Usha,
Welcome to HCM.
The fact that you have been on long term steroids, must have suppressed the adrenal gland from producing
corticosteroids.
Best way to reactivate the adrenal gland is by gradually tapering the
hydrocortisone dosage over a period of time so that the gland takes up that function., in due time.
Wish you all the best.
