Oh yep! I also have this. Ever since I was super young. Just turned 31 today and while it's dwindled, I still get them. My dad always told me "your lungs are sticking to your ribs". Lmao

You literally cannot breathe past a certain point without some outrageous pain. 

I had to hunch forward and take super shallow breaths and twist and contort until the pain went away. 

What a weird thing to just... have to do.

I stretch my arms straight up and try to breathe, it usually helps. Some people say they breathe through it but I don't feel like that's possible when it happens. fyi Im 27 and had it since I was super young too. Nobody I know irl has even heard of this before.
