Leopard gecko coughing , please help

[Gecko_gee]

My leopard gecko started to cough since ate tiny mice and it’s been two weeks already and stopped a few days now he started to cough again.
many one has any idea obcoughing ? Is that something chocked in his throat , or not enough water he drink? My gecko is still active, eat everyday, and poo everyday and I always let him walk around outside the box daily. The temp is around 25-28c and the humidity is around 60%
Anything I have done wrong ?
the vet that I would like to book is out of the town currently. Would like to know if anyone knows please. Thank you
You can look at the coughing video . My heart breaking thank you

Unfortunately the video won't play. If the gecko is eating and walking around it's not choking. I don't think it's urgent. When the vet gets back, make an appointment.

I don't have a clue. The gecko looks so good when it's not doing that, that it's hard to think of it as an emergency. How often does it happen each day?
