Chest tightness when taking a deep breath

A deep breath stretches the ribs and the muscles between them, so strain after coughing, exercise or an awkward movement can hurt or feel tight. Inflamed airways may make inhalation feel restricted and can occur with asthma or COPD. Sharp pain that worsens with breathing can involve tissues around the lungs. Reflux and anxiety can also alter chest sensations. Angina presents as pressure, often with exertion, and should not be ruled in or out from this symptom alone.

Stop strenuous activity, sit comfortably and breathe gently without repeatedly testing the symptom. Avoid smoke and note whether coughing, movement, position, fever or exertion changes it. Use only medicines prescribed for you, including an inhaler according to its instructions. Arrange a clinical review if the tightness lasts, keeps returning, follows an infection, or limits normal activity. A clinician can assess your breathing, chest wall and other relevant signs.

Seek emergency care for sudden or severe breathlessness, blue lips, fainting, confusion, coughing blood, a very fast heartbeat, or chest pressure with sweating or nausea. Get urgent advice when symptoms begin after a significant injury or are clearly worsening. Do not wait for a deep breath to become possible if you feel seriously unwell.

Ask what features distinguish muscle strain, airway narrowing, reflux and heart-related discomfort; whether you need tests; and what to do if symptoms recur. Tell the clinician when it started, whether movement or exertion changes it, and any cough, fever, wheeze or leg swelling.
