I had a stomach bug two weeks ago, vomiting and diarrhea but only for one night, other members of my family also caught it. however, i have had very bad wind and indigestion for the last 5 days which is uncomfortable and makes me feel nervous/anxiety?

Gastroenteritis: You likely have a case of Acute Gastroenteritis with associate dyspepsia and flatulence. This should resolve with time but if it does not you could have SIBO - Small intestinal bowel obstruction that requires possible antibiotic treatment. Other possibilities include IBS as well. You need to see a Physician or GI Doc for evaluation if does not resolve.
