A person attacked by asthma can really feel it coming. You feel your chest getting tighter and every time you inhale, it gets more difficult as if something is blocking the air passage as a result of the thickening of your mucus. The next thing you know it, you hear yourself wheez.
This asthma attack can be triggered by things you are allergic with. Some common triggers are perfumes, cold air, dust, smell of old magazines or books, pollen, and sometimes even the scent of the new bedsheet and pillow case. Some asthma also is triggered by the food you eat. Based on my experience, asthma attacks after eating chicken, nuts, pineapple, and chocolates.
