Allergy?: While taking an antihistamine or using a nasal steroid spray daily may help your symptoms, finding the source of your apparent allergic reaction would be best. Dust or dust mites are the most likely Try replacing your pillow with a non-allergic one. Try vacuuming under your bed and mattress itself. Then cover the mattress with a zippered impermeable cover that is made for people with allergies.
