I thought I might have liver problems or cirrhosis because of pains under my right rib that wouldn't shift- I got a lot of evidence off the internet that suggested I did have liver problems: all turned out to be false. Don't worry too much for now- if you're at something like stage 4 or cirrhosis, you'd know about it, and I'm pretty sure your numbers would be a lot worse. If you're not that far gone, there's a lot you can do to help your liver heal.
Get your tests done for piece of mind, and if there *is* anything that needs to be sorted, the sooner you catch it, the better.
