Will You Know If A Corn Kernal Went Into Your

Will you know if a corn kernal went into your lung? Coughing. Sneezing? I am freaking myself out. Was eating corn at lunch. Phone at work rang. Corn went down But didn't feel like it went to stomach. Stressed out now. Don't know if what I have been reading has caused my anxiety more. Just need to know if I should just get xray
