I'm not a doctor and have never heard of this from a liver cleanse. since the pain is under your rib cage, I would guess that toxins going into your liver are the problem. Read up on Coffee enamas on the curezone web page and see if that's a step you would want to take. If it were me I would do a coffee enema and plan on doing another liver cleanse in a week or so. I would also consider the 8 day fast to clean out everything. It sure appears to me that somthing wants out.
