Hi, portersmom. I am sorry you are having these problems. They don't sound like cancer or a pancreatic problem to me, but I am not a doctor. Speaking of doctors, I think you do need to tell yours about these symptoms. And watch out for dehydration.

I hope the sores are not malignant. Probably not.

And, yes, drinking heavily is not helping whatever you have.

I hope these symptoms will clear up soon.
