when breathing pain in chest

Pain in your chest when breathing can range from a simple muscle strain to a medical emergency.¹

When to Call 999 (Emergency)

Call 999 immediately if your chest pain is accompanied by any of these warning signs:¹

• A sudden, squeezing, crushing, or heavy pressure in your chest that does not go away
• Pain that spreads to your left or right arm, neck, jaw, stomach, or back
• Sudden shortness of breath or gasping for air
• Feeling sweaty, clammy, dizzy, lightheaded, or sick to your stomach¹²³⁴

Common Causes of Chest Pain When Breathing

• Pleurisy or Chest Infections: Inflammation of the lung lining (pleura) or infections like pneumonia often cause sharp, stabbing pain that worsens when you take a deep breath, cough, or sneeze.¹²
• Pericarditis: Inflammation of the sac surrounding the heart, which causes sharp chest pain that typically feels worse when breathing deeply or lying flat.¹²
• Pulmonary Embolism (PE): A blood clot in the lung that causes sudden, sharp chest pain and severe shortness of breath—this is a life-threatening emergency.¹
• Costochondritis or Muscle Strain: Inflammation of the cartilage connecting your ribs to your breastbone, or a strained chest wall muscle from coughing or heavy lifting.¹²
• Anxiety or Panic Attacks: Can cause sharp or rapid chest pain, fast heartbeat, and hyperventilation.¹²

What You Should Do

• If you have severe, crushing, or sudden rest-unresponsive pain, call 999 right away.
• If the pain comes and goes, is mild, or you are unsure of the cause, book an appointment to see a GP or contact NHS 111 for guidance.¹²³

Learn more To help me narrow this down, could you tell me:

• How long have you had this pain, and what does it feel like (sharp, aching, crushing)?
• Are you having any other symptoms like a fever, cough, dizziness, or radiating pain in your arm or jaw?

Chest pain when breathing (pleuritic chest pain) is commonly caused by inflammation in the lungs, heart lining, or chest wall muscles, though it can also signal a serious medical emergency. Because chest pain can stem from life-threatening heart or lung issues, you should seek urgent medical advice rather than self-diagnosing.¹²

When to Seek Immediate Emergency Help

According to the NHS Chest Pain Guide, you should call 999 or go to A&E right away if you have chest pain alongside any of these red-flag symptoms:¹²

• Sudden, persistent pain. You feel sudden pressure, tightness, or squeezing in your chest that does not go away after 15 minutes.
• Spreading pain. The pain moves to your arms, back, neck, jaw, or stomach.
• Severe breathing or heart issues. You are struggling to breathe, coughing up blood, or notice a very fast heartbeat.
• Systemic distress. You feel sweaty, dizzy, light-headed, sick, or faint.¹²³

Common Causes of Chest Pain When Breathing

If your symptoms are not an emergency, you should still contact NHS 111 or book an urgent GP appointment to find the underlying cause.¹

What to Do Next

• Monitor your symptoms. Sit down, rest, and avoid strenuous activity while you assess how the pain behaves.¹
• Do not drive yourself. If you decide to go to A&E for sudden or severe chest pain, ask someone else to drive you or wait for an ambulance.¹²
• Get assessed. As highlighted by the British Heart Foundation, conditions like pericarditis or chest infections require a proper medical exam to rule out heart trouble and get the right treatment.¹²

If you are safe and not experiencing emergency symptoms, could you share a bit more about:

• How the pain feels (sharp, dull, tight, or burning)
• Any other symptoms you have (such as a cough, fever, or recent chest injury)

I can help you better understand what might be going on and what questions to ask a doctor.

Chest pain when breathing in, especially when taking a deep breath, is something you should take seriously. It can have several causes, ranging from muscle strain to conditions affecting the lungs or heart.

Possible causes

• Muscle strain: Pain worsens when taking a deep breath, twisting or moving.
• Costochondritis: Inflammation where the ribs connect to the breastbone.
• Pleurisy: Inflammation around the lungs, causing sharp pain when breathing.
• Chest infection or pneumonia: May come with coughing, fever or breathlessness.
• Pulmonary embolism (blood clot in the lung): Can cause sudden chest pain when breathing and shortness of breath. This is an emergency.

• Sudden or severe chest pain.

A few important questions

I'd like to understand what you're experiencing.

1. Where is the pain: left side, right side, or middle of your chest?
2. Is it sharp, stabbing, aching or pressure-like?
3. Does it hurt only when you breathe deeply, or even when breathing normally?
4. Do you have a cough, fever or shortness of breath?
5. When did it start — suddenly or gradually?

Please don't ignore chest pain when breathing. Your answers can help me guide you on what might be causing it and how urgently you need to be assessed.
