Asthma attack
If you have asthma, the inside walls of the airways in your lungs can become inflamed and swollen. In addition, membranes in your airway linings may secrete excess mucus. The result is an asthma attack. During an asthma attack, your narrowed airways make it harder to breathe, and you may cough and wheeze.

Wheezing, sometimes just at night
Coughing
Shortness of breath
Chest tightness
 Other possible signs and symptoms may include: 
Runny nose
Nasal congestion
Eye irritation and tearing
 Occupational asthma symptoms depend on the substance you're exposed to, how long and how often you're exposed, and other factors. Your symptoms may: 
Get worse as the workweek progresses, go away during weekends and vacations, and recur when you return to work.
Occur both at work and away from work.
Start as soon as you're exposed to an asthma-inducing substance at work or only after a period of regular exposure to the substance.
Continue after exposure is stopped. The longer you're exposed to the asthma-causing substance, the more likely you'll have long-lasting or permanent asthma symptoms.
