Irritation from your building work may be triggering the cough again, but the underlying cause needs to be determined. In a person who has a
normalNormal saline flush chest x-ray and who doesn’t smoke the most common causes of cough are postnasal drip, chronic sinus problem, heartburn, and asthma. A chronic cough can also be a side effect of a group of medicines used to treat high blood pressure called angiotensin converting enzyme (ACE) inhibitors. You need to be seen by your doctor and have testing done to figure out what this could be and the best treatment. You may want to see a specialist, such as an allergist or pulmonologist. If using your salbutamol inhaler stops the cough for a period of time, it may be asthma.
To know for sure if your symptoms are due to a lung problem you will need to have testing done. Generally testing for a breathing problem starts with a simple breathing test called Spirometry. It provides detailed information about how your lungs are working. You exhale into a machine called a spirometer. The spirometer measures how much air you can exhale in the first second and how much air you can exhale total. For the testing to accurately measure how your lungs are working, it is important that you give your best effort when exhaling. It will show if there is obstruction in your airways. Sometimes this test is repeated after you have used a rescue inhaler.
Good luck--reconstruction CAN be awful for allergy sufferers; it was really tough on my son when they were doing building/reconstruction at ths school he attends. He missed 64 days in one school year.
