Occupational asthma signs and symptoms may include:  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.
