my 6 yr old daughter has been dealing with a breathing tic (we think) for over 3 months.  she continously takes deep breaths and at times, when outdoors but not overly exherting, she places her hands on her knees to breath in deeply while expanding her lungs.  her twice taken xrays look normal, according to her doctor.  we have taken her to a child pulmonoligist and my daughter was given a hemeopathic supplement that has not accomplished any change.  at times my daughter complaines of rapid heartbeat and at times nausea.  as she is sleeping all seems to appear normal.  my wife and i are considering bringing her to mayo to get to the bottom of this.  your thoughts?  my 6 yr old daughter is normal in ht and weight and has no medical history.
Respected User, hi sorry to hear about your issue.*This doesn't seem normal, there is definite underlying pathology causing her annoying symptoms of this level.*Reasons are related to Bronchi / Alveoli insufficient to pump enough oxygen, Heart valves related or intra-abdominal pathology compressing diaphragm.*She requires intensive work up in form of Pulmonary Function Test, 2D Echo Ultrasound abdomen, pelvis & if needed CT / MRI lung.*Treatment only comes after the 100% clinical diagnosis.*Till then what you can do at all
