YES!
Ugh, it's so annoying. That bone in my wrists is always sticking out and its annoying!
And with my back, I can't do a few yoga poses because it hurts the bones too much.
But I'm not anorexic or anything... I'm just skinny, even if I didn't work out, and all I ate was crap for a month, I'd hardly gain any weight, it just doesn't happen for me.
I have prominent hips and collarbones too.
