If I'm showing symptoms of jaundice what do I do?

I've had the palm of my hands yellow of about 2 months now. Last year I my doctor told me that I had high blood pressure does this have to do with my yellow hands? Someone told me that it was because I needed to drink more water but I was looking around the internet and it said that it could be jaundice. I'm really sacred. Can this go away? Do I need to make an immediate appointment with my doctor to have a look at me? Will it go away if I do drink a lot of water?
