Diaphragmatitis, also known as pleurisy. The exact treatment depends largely on its cause as well as the condition. If the diaphragmatitis is caused by tuberculosis due to Mycobacterium tuberculosis infection, it is necessary to go to the hospital, and in addition to the drawing of pleural fluid, it is also necessary to use anti-tuberculosis drugs as early as possible and in a standardized manner, such as isoniazid, rifampicin, ethambutol, pyrazinamide, streptomycin, levofloxacin and so on, which require standardized and sufficient courses of treatment. If the septitis is caused by bacterial infection, antibiotics such as penicillin, amoxicillin, cefoperazone, and roxithromycin need to be selected for treatment. If there are symptoms of pain that interfere with breathing and movement, pain medications such as ibuprofen and acetaminophen may also be appropriate. Additionally keep a follow-up appointment to adjust the treatment program at any time.
