Liver damage symptoms after resuming drinking for only 2.5 weeks
22f, 5'0, 88lbs, probably an alcoholic
I've been a heavy drinker of some description for around 5 years. My heaviest drinking period was around six months of drinking a full bottle of vodka most days. I got sober and spent six months sober on and off, with two straight months sober until 2.5 weeks ago.
I started drinking again about 20 days ago and have been drinking around 15 units of alcohol a day, also been taking codeine daily for that same period. Since resuming drinking, physical symptoms started almost immediately. I'm sleeping about 6-8 hours a night but am constantly exhausted, I feel like I haven't slept in weeks. I've been having pains in my upper right abdomen specifically and more generally my whole stomach area is painful to the touch as if it was bruised. I wake up shaking and in a cold sweat every morning and and don't stop shaking until the middle of the day normally.
I'm slightly worried because I know my symptoms line up with liver disease and hepatitis but I thought I had given my liver adequate time to heal in my two months sober. Is this just a really drawn out hangover or likely to be something more serious?
I'm not looking for mental health advice, only asking about the physical symptoms.
