I have recently acknowledged one of my ribs poking out and being a bit sore only when I feel around it. I am really worried about what this could be. It doesn't hurt that much which is good. It seems like it twists, and only happens when I bend, sit-up while laying down. Or am resting on my side/my elbow. It really worries me, it isn't noticeable on the surface but when I feel around it feels like it twisted around. It is kind of hard to explain but I hope I gave enough info. Also I am 13 years old in case that can help in any way.
