Hello dear I understand your concern Your symptoms could be due to parasite infection, inflammatory bowel disease (associated with blood in stool), irritable bowel syndrome, microscopic colitis. I would suggest to consult gastroenterologist and undergo complete clinical evaluation, stool tests, fecal calprotectin test, serological test for celiac disease, routine blood tests. Specific treatment depend on cause You can take meftal spas for pain Prescribed albenazole plus metronidazole Capsule sporolac Drink plenty of water and ORS solution Eat diet like banana, applesauce, rice, toast, yogurt and butter milk Hope this may help you Contact further if follow up needed Best regards Dr. Sagae
