What is causing VCD

My daughter (9) has been choking, unable to breath, many times (15-20) a day/night to the point of throwing up during many of these episodes.  We have been to the emergency room twice and to several specialists.  This has been going on now for about 10 weeks.  Finally she had one of these episodes in her pediatrician's office and he diagnosed her with Vocal Cord Dysfunction.  He referred her to a speech pathologist (trained at Jewish Health) and she told me that my child does have VCD but it is being caused by something that has not been diagnosed yet.  She said it sounded a lot like whopping cough and referred me to this website (www.whoppingcough.net).  This sounds exactly like what my daughter is going through.  My question is, if she has been immunized can she still get whopping cough?  Is there something else out there that may mimmic whopping cough?  What else could be causing this?  Her pediatrician has decided that he cannot help us anymore and has referred us to a pulmonary specialist but it will be 5 weeks before we can get in.  Can anyone help us?  Any ideas on where we can turn?

My daughter has been diagnosed with Paradoxical VCD. She has been dealing with this for three and a half years with misdiagnosis's then when it was finally diagnosed, nobody can find the trigger. We have done GI test for acid reflux, allergy tests, etc. We now think it is anxiety related but she could be having the time of her life then minutes later is having an attack. Anyone have any ideas for us to look at?
