I ate japanese eel(unagi) and got a bone in my throat halfway when i was eaying. I am uncertain of its original length, but i think it's at least a 3cm. Tried various methods (e.g. bread, water, milk, potato, vommiting,checking my throat where area and visible but no avail.) I understand that after removing it you still feel the same, but the thing is that i do feel the bone staying this the same place. I don't know if this is helpful, but this situation has lasted for about 6 hrs.

Thank you for helping! (:
