If a hard lump is felt above the stomach in the middle of the two ribs, if there is no obvious pressure pain, the initial consideration is the saber prominence. The saber process is a normal physiological structure of the body, and for weaker subcutaneous fat may make the saber process obvious, and this is not a situation to worry about. If the patient feels a hard lump and experiences discomfort, it is considered to be costochondritis, which may appear as enlarged and elevated rib cartilage with painful pressure, and can generally be treated according to the etiology: 1. Non-specific costochondritis: it is somewhat self-limiting and self-healing, and has a better prognosis. Aspirin, ibuprofen, acetaminophen, indomethacin and other non-steroidal anti-inflammatory drugs are commonly used for treatment. Physiotherapy, hot compresses, infrared microwave, etc. are commonly used to help reduce inflammation and swelling, reduce nerve endings irritation, promote blood circulation, and achieve the purpose of analgesia; 2, septic costal chondritis: also known as primary infectious costal chondritis, is less common, but untimely treatment may lead to prolonged deterioration of the condition. Surgery is usually performed to remove the diseased rib cartilage and is supplemented with antibiotic treatment such as dexamethasone. Topical application of Chinese herbal medicine Gold San can also effectively relieve local redness and pain. In addition, benign chest wall tumors such as chest wall fibrous heteroplasia, chondrosarcoma and osteochondroma, and malignant chest wall bone tumors such as chondrosarcoma, osteogenic sarcoma and giant cell tumor of bone are rare, but they mainly cause hard masses of tumors in the rib or sternal area, so that patients can palpate hard masses above the stomach in the middle of the two ribs. And diseases of abdominal organs, such as hepatitis, liver encapsulation disease, liver tumor, etc. cause hepatomegaly and hardening, which may make patients palpate hard lump-like masses, and patients are advised to go to the hospital for consultation in time.
