Hello. Welcome to healthcaremagic. It is very difficult for food particles to enter your trachea instead of esophagus
. Even if it occurs by chance you would have experienced instantaneous choking
and difficulty in respiration along with cough
and would have expelled it out. At that point of time a person could have helped you by standing behind you and holding his arms arnd ur chest and pressing on lower chest. if you face any respiratory problems consult your doctor.
Wish you good health.
