They have no idea what causes costo, but it can be very debilitating. I truly believe it is a symptom of other things happening in the body. It mimics gallbladder disease, and sometimes heart attack.

Forum might be experiencing costo but think there is something wrong with their gallbladders (so did I) :-). But I did have a diagnosis of fatty liver, and so I did liver flushes. I think they are exceptional.
But I think costo can come from the bowels or the lungs or other inflammatory problems too. That's how I found curezone, and I'm happy to say that after 4 years of chronic, intense pain, I am pain free now for 8 months. I feel very fortunate, and try to spread the word on other forums. Unfortunately they are very resistive to alternative medicines, and take so many drugs you wouldn't even believe it.
