Itching absolutely can be a sign of liver problems. If you have no rash or hives it may be the liver. I know when my liver enzymes were elevated 5x what they should be AST/ALT and the third which escapes me now I had horrible itching. No rashes at all. Support your liver. I eliminated meat and dairy for awhile and things gradually improved and enzymes went back to normal. Still taking care of my liver though.
