Worried about my Liver

Last week I had shooting pain straight up and down of my breast area. The night before I played a game of softball and I though I was just sore.  Until later in the day, the pain was worse.  Felt like a nerve was being pulled.  I couldnt stand up straight either.
I already had my Gallbladder out so it wasnt that.
I went to Urgent Care dr instisted that I had an Ulcer and gave me a GI cocktail and made me wait.  While I felt everything numb inside my tummy the pain was still there.
Then dr guessed it would be my Pancreas,  drew blood and sent me home.  The next day they called and said my test was abnormal and I need to see a Liver dr.

I am addicted to Diet Coke and drank over a case a day, including water-some....
I am trying to quit now but going through withdrawls.

My question is:  Do you think the problems from my liver arises from my soda drinking habit?

Our liver filters everything, and the jury is still out on the long term effects of artificial sweeteners.  This is a difficult question, and one I think many would love hearing the answer to. See the specialist and ask this question and then if you don't mind...I think we could all benefit from knowing if the diet soda caused this, so if you could post your findings, that would be great! I wish you all the best.
