Chest tightness for days: what to know

Chest tightness is a sensation rather than a diagnosis. It may occur with airway narrowing in asthma or COPD, irritation from acid reflux, muscle strain, anxiety, or a heart-related condition such as angina. The feeling may be pressure, squeezing, heaviness, or difficulty taking a satisfying breath. Notice whether it follows activity, meals, lying down, stress, or exposure to smoke, and whether rest changes it.

Pause strenuous activity and arrange a prompt medical assessment. Keep a record of when the sensation starts, how long episodes last, what brings it on, and any cough, wheeze, fever, palpitations, nausea, or pain spreading to the arm, jaw, back, or shoulder. Do not start someone else’s inhaler or heart medicine. A clinician may check your heart, lungs, oxygen level, and other possible causes.

Seek emergency care now for severe or rapidly worsening pressure, trouble breathing, fainting, confusion, blue or grey lips, cold sweating, or pain spreading beyond the chest. Urgent assessment is also needed when tightness begins during exertion or comes with marked weakness. Do not drive yourself if you feel seriously unwell.

Ask whether your pattern fits an airway problem, reflux, muscle strain, anxiety, or angina; which examinations or tests are appropriate; and what symptoms should prompt emergency help. Ask how to use any prescribed inhaler correctly.
