Welcome to HCM. From your history i think you might be suffering from allergic rhinitis
. Please understand that as far as my knowledge goes, allergic conditions cant be cured but only controlled. You are taking Montair/Montec LC and that is good for you. You can also steroid
combination nasal spray(Like Dunase/Combinase AQ) for your severe symptomatic relief. Mind it, although inhalation steroid has less side effects than systemic steroid, steroid should always be taken only under your Doctors supervision.
The condition you described that you are not even able to go to office for it, i think you are a candidate for steroid nasal spray.
Take care and thanks
