You need to see a doctor for this if you suspect a liver inflammation. The Doc should run some test for liver enzymes, hepatatis, etc, and then probably refer you to a gastroenterologist, who will examine your more thoroughly. You will also want an ultrasound of your liver. Why do you suspect this??
As far as for what you can do....standard liver protectants, but that's about it (milk thistle, NAC, ALA, etc).
