I am 17 yrs old. And am suffering wid dust allergy. Even due to very trace amounts of smoke or dust my nose start watering and gets blocked, I even experience a itchy throat. Doctor said I hd excess eusinophills in my blood. I went through allopathic medication but it was off no use. I am suffering a lot wid dis problem but I really don't know wt to do. I will be really thankful if anybody can help me.
