Since you have already used monitor and other medicines I would advise you to start on bresol by Himalaya. You are having an allergic condition and it can only be controlled by anti allergic medicines like levocetrizine allegra (fexofenadine) So continue allegra 120 for 1 months along with bresol. Where is a injection available in the market taking subcutaneously of which three times can help you getting rid of this condition for almost 1 year.
Next Steps
consult respiratory specialist if even after one month the problem persists
Health Tips
avoid travelling in the dust and pollution and sun
