How to cure dust allergies?
You can get a shot every week, and eventually it will go away. They are called allergy shots. (haha you probably know that.) Anyway if that is not a good solution for you then you can take allergy medicine. Hopefully that answers your question.
Ask your doctor to try the hyposensibilization therapy on you. This worked for my boyfriend. Although, it's very pricey.
clean and dust everyrhing so you don't have to worry about it
I clean my room very very often. It works :)
