Hi
My 3 year old fell out of bed, and when I went to pick him up I noticed a strange rhythmic clicking noise in his chest. At first I thought it was some kind of hiccups, but his vocal chords were not closed with each click, he was still crying from the fall. He then rushed to the bathroom saying he needed to get sick, retched once but nothing came up, and the clicking had stopped.
What could this be? Should I be worried?
