Hi, I have a breathing problem that so far no doctor or specialist can find a cure or reason for it happening ( NZ or Australia). every minute i will suddenly take a quick breath struggling to get air in. This isnt something i do intentionaly my body just does it randomly, This can last up to 6-8 weeks at a time, i am highly fit and it can worsen when i am playing reugby league or in the ring for my professional boxing. wake up one day and it will be gone, i havehad an ECG test done as well as the running treadmill test, Xrays, ultrasounds, everything comes back fine with my heart lungs etc, When im suffereing from this i also can not finish a yawn properly which is so frustrating. do you have any ideas
