Yes with your history of the stabbing and surgeries adhesions may very well be the source of the abdominal pain. It is less clear that these scar bands would be causing nausea or if you may have other reason for the nausea...
Pancreas related blood tests would include lipase and amylase ( enzymes from the pancreas) If these were elevated then it would indicate pancreatitis and that would certainly explain both abdominal pain ( typically mid upper and radiating to back)
The liver function tests would typcially include enzymes >>AST, ALT , Alk Phos >> elkevation could indicate inflammation of the liver =hepatitis of some form and this also would be typical to cause nausea and abdominal pain...
Other liver function tests may include Total Bilirubin, albumin and total protein...
Chemistry labs would include BUN and creatinine to look at your kidney function and electrolytes ( sodium, potassium. chloride, bicarbonate)
I would advise that you may consult a gastroenterologist if the problem is not quickly identified and helped.. you may have GASTRITIS as possible and very common cause > You may have an ulcer as a common cause of these symptoms.. If that then you may benefit from medication to reduce the acidity of your stomach secretions (Nexium, Prilosec, Prevacid, Dexilant, Aciphex, Protonix) >>
You may benefit from a bland diet and less GI irritants ( worth a try I think with your history) to avoid alcoholic drinks, coffee, hot/spicy/acidic foods( tomato based products, onions, peppers, citrus fruits) and avoid using NSAIDs such as aspirin, Aleve, Advil..
The best treatment for you depends on the underlying cause and this is in the process of being determined it sounds >>
