My husband accidentally choked on a piece of lemon seed or ice cube ( he couldn't figure out which one it was) while having drinks last night. He couldn't breathe for a few seconds but the situation was under control after sometimes after he coughed heavily but he still feels something stuck inside with a sharp pain in the right abdomen near lungs. Is it something serious or is it just the heavy coughing and the fast compressions given on his lungs to make him throw out any food? He doesn't have any coughing or choking issue anymore though and everything else seems perfectly fine.
