I'm experiencing these random single hiccups scattered throughout the daylike just one hiccup at a time but occurring maybe 10 or 15 times daily. They're quiet too. I've noticed them every day for the past three weeks. I know I have acid reflux and anxiety, but aside from that, I'm a healthy and active 23-year-old female. I'm really curious if having just one hiccup multiple times a day is considered persistent. Can you shed some light on this?
