What causes pain in the right side of the chest when breathing in and out?

Pain in the right chest during inhalation and exhalation may be caused by conditions such as rib fracture, tuberculous pleurisy, or pneumonia. The treatment varies depending on the underlying cause.

1. Rib fracture: A direct blow or trauma to the right ribs can result in a rib fracture on the right side. The fractured area may damage surrounding intercostal blood vessels, leading to symptoms such as chest pain, chest tightness, and cyanosis, which may worsen during breathing. Consult a doctor for possible treatment with medications such as cefazolin sodium for injection or cefoperazone sodium for injection to alleviate symptoms.

2. Tuberculous pleurisy: If the right pleura becomes infected with Mycobacterium tuberculosis, it can trigger an inflammatory response, causing adhesions in the pleural lining. This leads to friction during respiration, resulting in pain in the right chest when breathing in or out. If accompanied by dry cough, treatment under medical guidance may include rifampicin tablets or bromhexine hydrochloride tablets.

3. Pneumonia: When the body's immunity is weakened, it becomes susceptible to pathogen infections, causing inflammation or swelling of lung tissue. Such local inflammatory infiltration may also lead to the aforementioned chest pain. If associated with sweating and coughing, medications such as levofloxacin tablets or roxithromycin dispersible tablets may be used as directed by a physician.

In addition to the above causes, other conditions such as pulmonary embolism cannot be ruled out, and patients should seek prompt and appropriate treatment.
