my 29 year-old son breaths in and gets saliva down his wind-pipe; it happens rarely but scares us both; he suffers from hay-fever; do you think it could be Upper Respiratory Tract infection?
My grown-up son occasionally seems to choke in his own saliva which travels into his air-passage. It's really scary but he controls it. He suffers from hay-fever and has weak epiglottis. What to do?
