Have the liver checked. Ask the doctor to do full blood work up it not just the basic. I hope you have alerted your doctor and taken pictures. Also look at the whites of your eyes to see if they are off color.
Use white as your back ground, or put the hand on your leg to see if the color change is noticeable. If you don't eat them now add liver and beets to your diet. Grill the liver, no salt, it tastes better that way. I'm the only one in my family that touches it, besides the dog, lol.
