My granddaughter just returned from ER visit with dislocated elbow(3rd time it has happened). She screamed and cried during entire time (2 hrs) while they checked her out, X-rays and then popped it back . They gave her some codine pain Rx while there. She was in no pain when she got home and is asleep but making a hiccup noise while sleeping. Should we be alarmed that it is something with codine. I tried waking her up and she is sleepy and groggy but they stopped for a bit but now doing it again
