5. Rib fracture
A rib fracture is a break in the bones that protect the internal organs in the chest.
It can be very painful and lead to serious complications. One broken rib will not usually lead to complications, but multiple fractures can be life threatening.
Rib fractures usually result from a fall or blow to the chest, but severe coughing can also cause a fracture. A break on the right side can cause pain, swelling, and tenderness in that area.
6. Pneumothorax
Pneumothorax occurs when air escapes from the lung and gets into the space between the lung and the chest wall. It can lead to a collapsed lung.
This makes it difficult for the lung to expand when breathing and can cause sudden and significant pain or discomfort.
There are many possible causes,
- smoking
- conditions such as chronic obstructive pulmonary disease, asthma, and cystic fibrosis
- a biopsy in the lung area
- a blunt or penetrating trauma
Someone with this condition might also experience shortness of breath, a rapid heartbeat, and dizziness. Anyone with these symptoms needs urgent medical attention.

7. Pleurisy
Pleurisy is inflammation of the membranes that surround the lungs. This inflammation causes friction between these two layers of tissue.
Usually, there is a thin, fluid-filled space between the linings of the lungs and the chest cavity. When breathing in and out, the lungs glide smoothly over this tissue.
In pleurisy, the friction can lead to sharp and severe pain when breathing.
The condition can occur for various reasons,
- a traumatic injury
- pneumothorax
- pulmonary embolism
- conditions such as lupus, cancer, or pneumonia
Treatment and prognosis will depend on the cause. A person should seek immediate medical help if they have difficulty breathing or dizziness due to low oxygen levels.
8. Pleural effusions
In pleural effusion, fluid builds up between the layers of tissue outside the lungs. It can cause chest pain and shortness of breath.
Causes
- conditions such as pneumonia and tuberculosis
- chronic conditions, such as RA and lupus
- hemothorax
- exposure to asbestos
Breathing may get more difficult over time, so seeking help from a doctor is essential.
9. Pneumonia
Pneumonia is an infection of the lungs by bacterial, viral, or fungal organisms.
Symptoms
- a fever and chills

Chest pain can occur when a person is breathing and coughing. Individuals with suspected pneumonia should seek prompt medical help. Some people will need to spend time in the hospital, as the condition can result in life threatening complications.
