Shortness of breathe after yawning

I’ve been looking online to see if anyone else gets shortness of breathe as a result of yawning but haven’t seen that yet.  My case is that I yawn randomly, and then instantly I can barely breathe.  This lasts for about 30 minutes, and it’s been happening more and more. I used to get it as a child, but it went away until as of late. If anyone out there has this same issue I’d love to compare notes as I haven’t found a solution to this yet.  

About me:

Age: 33

Height: 6’3

Weight: 265

Activity: all over the place. I can be a lazy piece of crap all day, or just the opposite. 265 sounds like a heffer with cheese but I’m in pretty good shape. I can run a few miles, 17 pull-ups, 80 push-ups, 40 dips, fairly impressive stuff for a guy of my size.

-I drink roughly 2 large Dunkin’ Donuts iced coffees a day, Black.  If this is the cause, that’s sucks, because I’m not giving it up.

-I work out 4 days a week.  (I don’t know if anyone else with this, but while I work out I yawn literally every minute. Not during cardio, just weightlifting.) it’s very annoying, and I’m pretty sure at this point everyone thinks I’m fake yawning. You know what I mean. The fake nonchalant yawn people do to act like they aren’t experiencing an anxiety attack.

- I have alcoholic drinks 4 times a week.

-valsartan for high blood pressure.

I can’t think of anything else relevant right now but hopefully this will get the ball rolling. if anyone has any similarities or has any questions so I can find a link that would be awesome.

Hi mike, i suffer with this most days its like a feeling of not getting a full breath. Do you feel as though you are breathing right at the top of the chest and not deep enough if that makes sense. Its horrible i just tell myself i must be ok as im still hear the doctors have said it may be asthma but im sure more likely anxiety

Yes it feels like just the top. I’m pretty positive mines not from anxiety though.

I’ve looked into acid reflux too.   I read that might have something to do with it even without showing symptoms. I took some over the counter acid reflux meds and that seemed to kind of do the trick. But the shallow breathing lasts only like 30 minutes anyway
