I've just been diagnosed with the above fungal infection in my right lung. My pulmonary doctor said we need to wait 8 weeks to see what happens; she is also sending me to an Infectious Disease doctor at the University of Utah, USA. I'm concerned about doing nothing to treat this. Maybe the ID doctor will do something, though. ??? I would greatly appreciate your thoughts. Should I be concerned? I am 70 and also have a below average IgG antibody, which I'm told is the body's main antibody that fights fungal infections. Thank you.
