Hi, I have been working in Bangalore for the last 6 years. After I moved towards oldmadras road, due to lot of dust, I am facing bit of dust allergy(I think so).I feel bit uncomfortable in breathing sometimes during night(sometimes if its cold also). So, I use Otrovino nosal drops, it looks OK then. What do you think is the right cause for this and should I consult ENT specialist or allergy specialist? When I consulted a general physician first, he advised me of some medicines and otrovin. My nose is blocked and I feel I have flum for long periods(sneezing nose even though I dont have cold)
