Liver Flush... how do you know?

I've been having digestive problems for the last 4 months and the doctors haven't been able to find out what is wrong.

How will I know if a Liver Flush could help me??

I had an ultrasound 3mths ago and they said everything looked fine. Does that mean that my liver is probably not the issue, or could problems with it have been overlooked?

I've also been having side pains as well as the discomfort and major bloating in my stomach, but it has been on my left side just under the bottom of my rib cage, has anyone experienced this?

Thanks for the help,
