Hi, Welcome to Health care magic forum.
                   As you describe, it appears to be the food 
poisoning, means the infection in the intestines, due to infected food.     
                   It is advisable to to consult the E.R, for 
medical help.You may need to have the antispasmodics, and infusion of the fluids to correct the 
dehydration.    
                   I usually prescribe to my patient with such symptoms infusion of 2 units,injections of cefotaxim,
dicyclomine hydrochloride, and tablets of 
ofloxacin,
ornidazole, 
ranitidine.   
                   Avoid taking potato, other tubers,tomato,egg, chicken,and and sea foods. 
                   Wishing for a quick and complete recovery. Thank you.
