That is indeed good news! It's always a relief to get to the bottom of problems and get them fixed!
I went to a Physical Therapist (PT) for neck and shoulder issues, and he said I wasn't breathing properly! I was always breathing from the top of my lungs, therefore always lifting my shoulders to help & always aggravating my neck/shoulder issues. He had me practice deep diaphragm breathing. It felt weird! But I can deal with that!
Improper breathing explained a lot of issues I had dealt with over the years. It's SO helpful to know, and to know what to do about it
Funny, but I always had a very small waist, and you have such a tiny waist. Do you think we 'little waisted' people are less likely to let our diaphragm expand somehow? Do we wear tighter waistbands, belts, whatever because we can, but then it affects breathing? Inquiring minds want to know. . .
