Hi, I'm suffering from dust allergy since from 8 years. Whenever I exposed to dust. I get sneezes continuously. If I use nasal spray. I will get relief for two or three days. Again the condition is same. And I'm effected with asthma too. And my nasals will block always. Only one nasal will open. I will get yellowish mucous from my nasals sometimes. Sir. Please suggest me what to do. I used homeopathy for 9 months. And that was worked good for sneezes. But my nasals is blocking. I'm not able to inhale air freely through my nasals. Only one nasal will work for inhale air. So please suggest me to get rid of this problem.
