I am suffering from dust allergy for the past 10

Patient: I am suffering from dust allergy for the past 10 yrs. It all started after I came in contact with the odor from a agarbathi factory next to my house. I consultaed many doctors and they said that it was an allergy and a doctor even told that it was asthma. I regularly have watery nose, sneezing and teary eyes. But still I have not found a perfect solution for the problem. Can you please help me ? I have my board exams in 7 months and I do not want it to affect my studies.

Symptoms: Running nose, sneezing and teary eyes.

Doctor:
