Hi...hope you are feeling a bit better now. People don't feel pain in the liver until the very last stages of liver disease, when it is virtually too late to do anything about it (irreversible damage). So your pain would be more likely to do with the gall bladder, maybe inflammation, which could lead to gallstones if you continued to drink heavily more regularly than you do at the moment (which doesn't seem too bad to me). I wouldn't worry that you have done permanent damage to your liver and I hope you have a great New Year!
