I get that feeling sometimes, the feeling like my ribs are squashing my lungs, especially when I breath out. When this happens I assume I am having an asthma attack ( I got asthma from bronchiolar pneumonia at age 17) and I use a bronchiolar inhaler and it stops the spasms or what ever you want to call them. but I am left with feeling jittery. I think I also have heart arthimas when under anxiety or severe stress. My resting heart beat is 95 and jumps to about 120 or more during these episodes, but my blood pressure is only about 110/60. Iam only 34 so I know it has nothing to do with menopause.
