I was eating a salad and felt a little piece of lettuce go into my trachae. I coughed vigorously and felt like I got everything out of my mouth but still felt like their was something down my windpipe. I have not been coughing or wheezing and I have been breathing normally. It has been 24 hours. But still feel like something is down there and it feels irritated. I have been trying to cough it up but nothing comes up. Am I just going crazy? I am 26, female, and healthy!
