In the last 2 days my eyes starting looking a bit yellow. Could this be a sign of a liver related problem?
Yes, it could be that or other things. You need to go see a physician and have them evaluate you.
Absolutely yes and should be checked immediately
It could be a medical condition if this is new. It needs to be worked up. Often it is due to too much bilirubin, and that could be a sign of liver infection or failure.
