The lungs can ache quietly, without fever or a severe cough. Sometimes it happens that a person gets used to the symptoms and does not attach importance to them. If these symptoms are repeated and the pain or discomfort increases, do not delay the visit to the clinic: - Shortness of breath with normal exertion. In the past, climbing stairs or walking at a fast pace was easy, but now there is not enough air. - Prolonged cough. If it lasts for weeks or keeps coming back, you should understand why. - Wheezing or noisy breathing. Especially if you haven't noticed it before. - Respiratory infections: frequent bronchitis, pneumonia or other diseases. - Phlegm - if it lasts a long time. - Pain or discomfort in the chest for no apparent reason or if the discomfort appears or intensifies with movement. - Weakness. If your usual physical activity suddenly becomes much more difficult. When you need an ambulance If you have sudden, severe shortness of breath, sharp chest pain, blue lips or face, confusion, or a rapid deterioration in your health, call an ambulance immediately. Important: One or even several of these symptoms does not mean you have lung disease. Don't self-diagnose - trust your doctor!
