Hi, Thanks for posting your query. With the available described symptoms, there could be possibility of gastroenteritis or intestinal obstruction. Other possibilities could be diverticulitis and fecolith impaction. You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up. You should go for complete blood count, erythrocyte sedimentation rate, ultrasound imaging, and serum electrolytes, renal function test. If your condition won t improve then you should also go for colonoscopy. You should take complete antibiotic therapy, antispasmodics, probiotics, antipyretics, if needed. You should maintain your hydration status by taking potassium rich liquids. Take soft diet along with yogurt and banana. Avoid milk and all milk related products. Take care, Dr. Mayank Bhargava
