Thanks for your query and an elucidated history. Your symptoms still look to be a form of gastroenteritis and the hard stools might have been due to Operative you might have been given. I would advise you the following:Get a proper course of an antibiotic, metronidazole, probiotic and go for soft bland diet. Get the following investigations:Blood-CBC- Tidal for Typhoid as these symptoms fit into the description of Typhoid. Urine and stool tests;Ultrasonography for appendicitis or other inflammatory conditions. Consult a Gastroenterologist if the treatment fails for further investigations, diagnosis and proper treatment.
