My son had a pistacio nut lodged in his lung for a week last summer. He had no use of it for a week. He now has had 3 bouts of pnumonia in the same area in less than 9 months. Could there be damage from not using the lung or damge from the nut? Our pediatrician is talking with a doctor about it, but just wanted to know if anyone ever delt with something like this? Thanks.
