This sounds uncomfortable. Sorry for the experience. Not long ago I was having a snack of slivered almonds. They were cut thin and kind of sharp. I felt like one attached to the side of my pipe going down. That's what it felt like. I kept trying to cough, hack it up, drank lots of water. Eventually I was like "oh well". And once I said that, I stopped thinking about it and I was fine. It's doubtful that anything is lodged there. But only you will know. Good luck
It could be from swallowing something wrong -- you know, going down the wrong pipe or when you swallow a pill and it doesn't go down smoothly. But really, there's no way for us to know but it's unlikely spaghetti and sauce would get stuck -- they're rather slithery.
