I am a 26 year old girl, university student. About 3 or 4 months ago, I started getting pus in stool. Before that I suffered from gastritis on a few occasions. I took medicine and became alright. Then I start geting pus in stool . There are no other signs and symptoms like abdominal pain etc. I am very worried. I took metronidazole for 5 days but in vain. Please tell me a possible diagnosis and treatment.
Thank you in advance
