Guys we don't have any Rehab or clinics to help with Lung Problems in our country. As mentioned before I've got Mild / Moderate emphysema (Fev1 varies between 67% to 81% in 4 consecutive blows) and got a description for Foxair Inhaler. I must use it once in the morning and once at night time. I rinse my mouth and take a drink of water after I used it. I however got a problem - I sing a lot in church and other places. Sometimes my vocal chords goes hoarse or cut of completely - can the Foxair be the cause of this and if so what to do?
