You don't mention whether you have very loose BMs. If you do, get a stool culture checked for bacterial pathogens & parasites. If culture is negative, you may have a viral intestinal infection which usually resolves in A week or so. At this time drink adequate fluids,eat a soft bland diet and your physician may be willing to order an antispasmodic medication like dicyclomine to take before meals.
