Left rib pain can be caused by trauma, costochondritis, lung disease and other reasons. 1. Trauma: Trauma can lead to bone damage in the rib area, which will prompt the left rib pain. It is recommended that patients go to the hospital to complete the corresponding examination, and then symptomatic treatment. 2. Costochondritis: this condition may be related to viral and bacterial infections. It is commonly seen in infectious lesions or after overwork, without obvious trauma to the left side of the rib pain. You can use some anti-inflammatory and pain-relieving drugs, such as procaine and non-steroidal anti-inflammatory drugs, under the guidance of the doctor. 3. Lung disease: patients with left rib pain may also be due to inflammation of the lungs, which can cause pleural adhesions, usually in the respiratory pleural pull resulting in pain. You can follow the doctor’s instructions to take oral antibiotic drugs to make the symptoms reduced, such as cefixime capsules, cefradine capsules and so on. It is recommended that patients do not overwork, drink more boiled water, eat more fruits and vegetables, do not eat spicy stimulation and greasy food, avoid smoking and alcohol. If the condition worsens, consult a doctor in time. All of the above drugs need to be used in strict accordance with medical advice.
