As you describe it appears to be the food poisoning, means infection of the foods, they need not be the junk food related. Sometimes the home foods also get infected due to storage problem.  I advise you to consult a doctor for diagnosis and treatment. He may need to have infusion of I.V.fluids for correction of deny Chat Doctor.  I usually prescribe to my patient with such symptoms injections of metaclopramide, cefotaxime, tablets of lactic acid bacilli, ofloxacin, and risperidone, and operative.  Wishing for a quick and complete recovery. Thank you. </s>
