2. A dry cough is a common sign you have pulmonary fibrosis.
Most coughs are wet, but when it’s dry, this should concern you. A lot of people who smoke have a dry cough because they have damaged their lungs over the years. Second-hand smoke can cause the lungs to become diseased as well. As long as any hazardous substance is able to get into the lungs, damage can be done. Even if you drink water, the cough will remain dry.
It is even worse, if you’re coughing constantly. This will cause chest pain. Even though the damage has been done to your lungs, you need to stop smoking or being around the substance that is causing you harm.
When you persistently cough, it could cause you to vomit. If the doctor suspects that you have pulmonary fibrosis, you may be given medications that will help with the cough and lung disease.
