My father(60), suffered for flu for long time. By it, water was filled in lungs of him. It was removed by injections & also Tuberculosis meds were given. Now they are fine. But, doctor started cetrizine & other anti allergy meds with asthma meds & said you need to take them lifetime. Went to government hospital & they suggested go in big hospital & do surgery as some foil or diaphragm is affected due to water. Even after taking meds, my fathers breathes heavily, need suggestions what to do.
