@jasmine321 There several members on thos site who were treated successfully with lavage. @pfist (Shari) I believe is one of them. Are you familiar with the procedure? I know that it is done with bronchoscopy and they squirt a small amount of saline into your lung and then suction it out. It is a lung cleanse of sorts to remove phlegm (and with it, mycobacterias) and mucous plugs. It is sometimes used for people who have the type of mac that causes cavities in the lung. How confident are you that your doctor knows how to treat this disease? Do you know what specie of mac you have?
