Shortness of breath, constant yawning, tight chest

[Kittencuddler]

I have had some of what you are having... I yawn and yawn, and can't stop, I too yawn so much, it makes my jaw and throat hurt.. I don't get really get the shortness of breath, not really the same time as yawning... If you ever find something out let me know.. I went to my dr. but he said he has never heard of anything like what I am experencing... I wish you luck...
