What should you know about tightness in chest when breathing?

Asthma can cause chest tightness with wheezing, cough, or variable breathing difficulty. COPD may cause ongoing breathlessness and reduced exercise tolerance. Reflux, a chest wall strain, or anxiety can also make breathing feel restricted. Angina may cause pressure during exertion. The timing, triggers, associated symptoms, and examination matter more than the sensation by itself.

Stop activity, sit upright, and try calm, comfortable breaths. Move away from smoke, dust, or another known irritant. Follow your clinician's written plan if you have asthma or COPD, including use of a prescribed inhaler. Do not borrow someone else's inhaler. Write down whether the tightness follows exercise, cold air, meals, infection, or stress and whether it improves with rest.

Get emergency help for severe breathing difficulty, inability to speak normally, fainting, confusion, blue or grey lips, sudden chest pressure, coughing blood, or pain spreading to the arm, jaw, or back. Arrange prompt care when breathing tightness is new, worsening, recurrent, or not settling with your prescribed plan.

Ask whether lung function testing, an examination, or heart assessment is appropriate. Share your exposure to smoke, allergies, recent infection, activity level, reflux symptoms, and the exact response to any prescribed treatment.
