Hi. It seems possible that the fish bone is still stuck in your throat since you are unable to swallow. It may be too thin or tiny for the X ray to pick it up. If I were your treating physician, I would advise the wait and watch approach here since we are not sure if the bone is still stuck or it has created injury to the throat wall. Both will present exactly in the same manner and the body cannot differentiate injury from foreign body. If in 24 hours your swallowing improves than it is probably an injury (pain reduces or able to swallow saliva with some discomfort). If the pain worsens and saliva drools because you are unable to swallow at all then that is indicative of a Foreign body and exploration under anesthesia may be required. If in 24 hours a new site for pain develops or you start to have a fever then it is also suggestive of the bone being stuck. If any of the features suggestive of a foreign body occur in 24 hours then get yourself admitted in the ER for further management. If you start to improve then allow the throat to heal. You should be fine in a week. There is nothing there that cannot be treated so do not stress yourself out too much either. Let me know how this turns out.
