You might not physically have felt it but those genius nerves in your throat knew it was there. That tickle to cough was them warning you. “Something is in here, cough @pkbites !”
I’m pretty sure there are little folds and crevices in pharynx and that seed was hiding and irritating a tiny amount. Making you cough.
Yeah, I have had a few patients over the decades who had such acute symptoms after inhaling a bit of food, often things like popcorn and other seed-like material. And it’s not unusual to NOT feel any symptoms in your throat if the foreign body just drops down into the lower trachea or below it.
Glad you coughed it up. Sometimes bronchoscopy is needed to remove such things. Watch out for recurring cough, fever, purulent phlegm, as it could signal a bacterial or inflammatory pneumonia. Not all that likely, but still a possible complication. Contact your doc/ER for signs/sx of respiratory distress.
I had to Google that (I know what phlegm is). That got me on to sputum. Many say “moist” is the most unpleasant word. I nominate “sputum.” Phlegm is up there too. A bit of advice…probably do not want to Google these things.
…characterized by thick, opaque, yellow, green, or brown phlegm, signifies an underlying infection or inflammation, often indicating an increased white blood cell count (neutrophils) in the airway.
I have an annoying gap between my back teeth and a late developing wisdom tooth. It’s really difficult to brush or floss and food sometimes gets stuck in there. A few months ago I started to feel some pain from it so I dug around with a sterile needle and managed to pull out a sesame seed. It was 2 weeks since I’d last eaten anything with sesame seeds on and the seed had actually started to sprout in there. Could this be a new gardening opportunity?
