Chronic inflammation of the middle lobe of the left lung and the lingual segment of the upper lobe of the left lung is most likely due to infectious chronic pneumonia, and should be treated with antibiotics and oxygen in conjunction with your doctor. Generally speaking, chronic inflammation of the right middle lobe of the lung and the left upper lobe of the lung is caused by bacterial infection, which is often treated with penicillin, erythromycin and other drugs in the clinic. For streptococcal infection can be treated with penicillin drugs, for mycoplasma, chlamydia, legionella infection can be treated with erythromycin and azithromycin. Oxygen therapy is also very helpful for this group of patients. Due to lung infection, it can lead to narrowing of the bronchial tubes, obstruction, and poor breathing, and the use of oxygen therapy can help to improve the symptoms. Chronic inflammation of the middle lobe of the right lung and the lingual segment of the left upper lobe requires targeted medication after clarification of the invading pathogen, and may also be caused by Klebsiella pneumoniae infection, which should be further investigated on the advice of a physician. All of the above medications should be used under the supervision of a physician, avoiding self-medication.
