Abdominal pain, diarrhea lasting 1 month is dangerous?

Question
Hello doctor,
More than 1 year ago I had a colonoscopy, I had acute colitis and was treated within 3 months. Now I'm getting better but now I have diarrhea when I have diarrhea, when the stools are small and flat, they don't form a mold. Every time I eat, my stomach hurts, after going to the toilet, my stomach hurts and I want to go to the toilet again. Since I had a fever, sore throat, and taking antibiotics and antipyretic pain relievers, I have had diarrhea and abdominal pain for almost a month now. Doctor let me ask if abdominal pain, diarrhea lasting 1 month is dangerous? Thank you doctor.
