I think you need a full liver evaluation. You need a complete hepatic panel done and further investigation into our liver. The symptoms you describe can be from liver problems. What was your platelet count? I'd want to know more about the albumin and protein issues, those can be related to the liver.
If you drink alcohol, I suggest you stop until you get to the bottom of this. Extremity swelling is worrisome. Do you have spider nevi? Little tiny broken blood vessels on your skin?
What were your liver enzyme readings for AST and ALT?
DId you see a gastroentrologist or a family doctor?
Did they check your kidneys?
