Hello I Have Recently Stoped Drinking Heavily And Am On

Hello I have recently stoped drinking heavily and am on day five now. I have a issue with my bottom ribs touching my hip bones creating pain when I gain or lose weight. It seems to take a bit for my body to adjust to the new size. However because I have stoped drinking I am cocernex as the pain is also located more close to the bottom ctr left and right of the ribs. I was wondering if the pain could travel there as the ribs are agitated or if I may have a pancreatic or liver issue not sure. It odd it is both sides. Do you have any thoughts. I know when you stop drinking you can have abdominal pain so this may be that. How long do you think it will continue... I read that withdrawal should get better in about two weeks.
