My grandfather had something quite similar and it turned out to be a polyp in his sinuses. It really began with his nose running constantly. Then one day, the polyp grew out of his nose quite quickly and he had no doubt then! I agree with the others in that you should go to and Ear, Nose and Throat Specialist. If you have been going to one with no luck, find another. They are not all wonderful so it might be a good idea to ask others whom they might have used or do a bit of research online in your area. Good luck to you. As for the others, just tell them you are working on it and are aware of the problem. I'm sure they smell like roses themselves, NOT! Some people are very inconsiderate, but do check into this further for your own health.
