What causes pain below the left rib cage on the front chest?

Pain below the left rib cage in the front of the chest may be caused by external trauma, or may result from conditions such as costochondritis or intercostal neuralgia, and targeted treatments can be applied accordingly.

1. External Trauma

When the chest suffers impact or compression from external forces, it may lead to muscle pain or even rib fractures, causing localized pain. If there is no fracture, symptoms can be relieved with local ice application. In cases of rib fracture, medical treatment at a hospital for immobilization is required.

2. Costochondritis

Viral infections or chronic strain of ligaments around the costosternal joints may lead to costochondritis. Inflammatory irritation can affect nerves, resulting in dull or mild pain in the left chest area. Symptoms are generally relieved with local heat therapy, or medications such as Mai Luo Shu Tong Wan or glucosamine hydrochloride capsules, taken as directed by a physician.

3. Intercostal Neuralgia

Conditions such as osteophyte formation in the thoracic spine, thoracic disc herniation, or thoracic scoliosis may compress the intercostal nerves in the chest, leading to nerve pain along the left ribs. Pain relief can usually be achieved under medical guidance using medications like carbamazepine tablets, phenytoin sodium tablets, or pregabalin capsules.

Besides the above, myocardial infarction involving chest muscles or thymitis may also cause pain below the left rib cage in the anterior chest. It is recommended to promptly visit a hospital for a chest CT scan and receive appropriate treatment based on the specific diagnosis.
