The pain you're experiencing under your left chest when you breathe could be due to a number of reasons, the most likely being pleurisy of the left lung.
Possible Causes of Pain Under Left Chest When Breathing
While pleurisy is a common cause, other potential explanations exist. It's important to seek medical advice for an accurate diagnosis and appropriate treatment.
- Pleurisy: This involves inflammation of the pleura, the lining surrounding your lungs. When you breathe, the inflamed layers rub against each other, causing sharp pain. The pain can worsen with deep breaths, coughing, or sneezing. Pleurisy affecting the left lung can definitely cause pain under the left chest.
- Symptoms: Sharp chest pain (especially with breathing), shoulder pain, dry cough.
- Musculoskeletal Pain: This type of pain originates from the muscles, bones, or cartilage in your chest wall. It can be caused by:
- Costochondritis: Inflammation of the cartilage that connects your ribs to your sternum (breastbone).
- Muscle Strain: Overexertion or injury to the chest muscles.
- Lung Conditions: Other lung-related issues could contribute to the pain:
- Pneumonia: An infection of the lungs that can cause inflammation and pain.
- Asthma: While usually causing wheezing and shortness of breath, chest tightness and pain can also occur, particularly during an asthma attack.
- Heart Problems: Although less likely, chest pain, especially on the left side, should always prompt consideration of heart-related issues. Angina or other cardiac conditions might manifest in this way. Seek immediate medical attention if you suspect a heart problem.
- Anxiety/Panic Attacks: These can sometimes manifest as chest pain or tightness, making it feel difficult to breathe.
- Acid Reflux/GERD: While usually felt in the center of the chest, the pain can sometimes radiate to the left side.
When to See a Doctor
It's essential to consult a doctor if you experience persistent or severe chest pain, especially if accompanied by any of the following:
- Shortness of breath
- Fever
- Cough
- Dizziness
- Sweating
- Nausea
Diagnosis
A doctor will likely perform a physical exam and may order tests such as:
- Chest X-ray: To visualize your lungs and check for abnormalities.
- Electrocardiogram (ECG): To assess your heart's electrical activity.
- Blood tests: To check for infection or other underlying conditions.
