Hello and welcome to health care magic. Thanks for your query.
There are many conditions in which we see foul smelling discharge from the nose like- sinusitis
, bacterial infection, deviated nasal septum
, polyps in the nose, foreign body impaction
in the nose.
As you have stated you are hydrocortisone
dependent, so it seems like you are having infection again ( sinusitis).
Usually steroids are known to reduce the functioning of immune system and increases the risk of frequent infection.
I would suggest you to consult ENT specialist
and to undergo complete ear, nose and throat examination, to look into the cause for foul smelling discharge through nose .
Wish you all the best
