So I had fish for dinner. I felt a sharp pain in my mouth, but don't know why but decided to swallow it instead of spitting it out. Now I don't know if it stuck in my throat or did it went down. Now I keep feeling there is something stuck in my throat. I'm in no pain even when I'm swallowing.
It's often difficult to tell the difference between an esophageal abrasion and a foreign body just by how you feel. If you get it checked out and it's just an abrasion, no biggie; if you don't and it's a foreign body, it could result in infection or perforation.
From an EM website:
All patients who complain of a foreign body of the throat should be taken seriously. Even relatively smooth or rounded objects that remain impacted in the esophagus have the potential for serious problems, and a fish bone can perforate the esophagus in only a few days.
Depending on its size, it hurts, it makes you cough, and swallowing food will worsen symptoms. The tendency is for symptoms to get worse if that foreign body isn't removed or carried down to the stomach. If you don't seek medical attention, bacteria may invade the sub-mucosae and infect the area. Therefore, if you feel you've swallowed something that got stuck in your throat or oesophagus, look for an E.R. immediately.
