I've had hiccups for the past few hours and really shallow breathing breathing. What do
Medfag here. There are dozens of causes of hiccups. Your diaphragm may be irritated, you could be in a low-oxygen environment, have eaten too much, air trapped in the stomach, or stress. Go outside, put on a meditation tape, and do some deep breathing. If it persists for more than 24 hours go to the emergency room.
