Multiple pus cells in your stool report indicate a bacterial gut infection, such as bacillary dysentery. To treat this, you will likely need a course of antibiotics (like Ofloxacin or Ciprofloxacin), sometimes combined with Metronidazole or Ornidazole, to clear the infection. For the stomach ache, an antispasmodic medication like Dicyclomine can provide relief. Because antibiotics require a prescription and specific dosages based on your health, you must consult a doctor or gastroenterologist immediately. In the meantime, prevent dehydration by drinking plenty of fluids or Oral Rehydration Salts (ORS) and eating a bland diet.
