Hello, I was just wondering if there would be a common cause for stomach pain (normally localised to the upper right quadrant), diarrhea and sometimes vomiting only after eating. Today I haven t eaten and I feel fine just tired but guessing that is a lack of nutrients due to the illness and no food. This has been going on a week. I noticed today my finger joints (both joints where fingers bend not where they connect to the hand) are swollen and dark. No fever and unless I eat I feel fine.
