Okay, So it feels as if it’s the bottom ribs that touch and it used to only occur sometimes mostly when I would lay to my side. But I now notice it more often. It causes me no pain but it’s not necessarily comfortable to have them rub together.i feel it often when I breathe they’ll click kinda back and forth as my lungs expand and contract. I’m 5’ even and around 115-120 lbs. can anyone tell me about this or does anyone else have this problem? I’ve heard of something similar but frequently hear how it causes pain.
