Obviously I'm not a doctor.. but you can't actually have pains IN your liver, the pain is from the inflammation of the liver, hurting the surrounding areas because of it's hardness/increased size, when there's something yucky going on inside it.
I hope you're ok!
I had this type of pain when I was drinking, I'm sure my liver was gigantic. Yet another great thing about not poisoning myself anymore. I hope you're feeling better soon!
