Stomach bug? Sounds like minor stomach upset likely due to a virus. Keep yourself well hydrated, call your doctor if not improved in 2-3 days.
Lower left discomfor. Discomfort in this area of the abdomen may come from abdominal wall muscle or from the lower colon. The latter could be due to diverticulitis or a viral intestinal infection. The former is the more serious and requires antibiotic treatment. If the discomfort persists and there Is tenderness and fever, see your physician for evaluation. Vomiting suggests a viral infection that improves in a few day.
