What causes a dull pain in the right chest cavity?

Generally, mild pain in the right thoracic cavity may be caused by muscle strain, pleurisy, costochondritis, myocarditis, tuberculosis, or other reasons. The condition can be improved through appropriate rest, medication, and other treatments. If discomfort persists, it is recommended to seek timely medical attention at a hospital for symptomatic treatment under a doctor's guidance. A detailed explanation is as follows:

1. Muscle Strain

Intense exercise or overtraining may cause strain or overuse injury to the muscles in the right thoracic cavity. Appropriate bed rest is recommended, avoiding exertion or strenuous activity involving the right side of the chest. Pain can also be relieved through hot compresses or massage.

2. Pleurisy

Pleurisy may result from bacterial, viral, or fungal infection of the right pleura, causing local inflammatory reactions. Under a doctor's guidance, medications such as penicillin V potassium tablets, aspirin tablets, rifampin tablets, and others may be used for improvement.

3. Costochondritis

Trauma, infection, or overuse may lead to costochondritis, presenting as unilateral chest pain and swelling. Anti-inflammatory and analgesic medications such as ibuprofen tablets, celecoxib capsules, prednisolone acetate tablets, and others may be used as directed by a physician.

4. Myocarditis

Myocarditis is usually triggered by viral infections and may present with chest pain accompanied by symptoms such as fever and palpitations. Under a doctor's guidance, medications such as furosemide tablets, isosorbide mononitrate sustained-release tablets, compound captopril tablets, and others may be used for improvement.

5. Tuberculosis

Tuberculosis is an infectious disease primarily caused by Mycobacterium tuberculosis infection, which may cause mild pain in the right thoracic cavity, along with symptoms such as coughing and night sweats. As directed by a physician, medications such as isoniazid tablets, rifampin capsules, streptomycin sulfate for injection, and others may be used for symptom relief.

In daily life, it is important to ensure adequate rest and sufficient sleep, while avoiding strenuous exercise to promote physical recovery. Additionally, maintaining a light diet and avoiding spicy or irritating foods, such as pepper and chili peppers, is beneficial for overall health.
