I have severely asymmetrical ribs. Everything I can find online talks about rib protrusion, which seems common in women, ie- people say one side of their rib cage sticks outward more than the other. However, in addition to this, it actually appears I could have an additional rib on one side - the left side of my rib cage ends three or so inches further down on my torso than my right. Is there anywhere I can find information regarding this? and if I do have an extra rib, is there anything to worry about long term? when doing strenuous exercise or bending fully forward sometimes i feel a snap in my left side, as if muscle gets caught under my last left rib and it's very awkward and uncomfortable. In addition to this, it's a clear physical deformity that can be seen any time i am in a bathing suit or don't have a shirt on. I can post a picture if that is possible. Thanks very much.
