When eating dinner tonight ( a casserole with corn and beans), I accidently inhaled and I coughed for a period of time. Then I felt it (corn) in the area of my trachea and esophagus. Now it feels like it is in my air pipe. If I take a deep breath I instantly cough. I can take shallow breaths without a problem. I am sure it will continue to move down, but am concerned about it going into my lung etc and infection. Does this need any intervention. It has been a couple of hours now.
