Does anyone who deals with the "hug" also have a difficult time getting a good, deep breath?

I wouldn't call this "shortness of breath"......it's just more difficult to get a satisfyingly deep breath. Kind of like stopping a yawn before it's all finished. That feeling of not quite getting the whole thing.

Whenever I deal with the "hug" I have a nagging pain in my right side right below my underarm and above my waist. Feels like sort of a "catch" you get in your side when you run too much (haven't done that in years ).

It's much more noticeable when I lie down and especially on my side. So, I sleep on my back 99% of the time. Tried using another pillow but that just made it worse. Seems the more my head is inclined the worse it gets.

Does anybody else deal with this and, if you do, what has worked for you in terms of helping these symptoms?
