This topic is about someone who, eight years after being treated for colorectal cancer and living with a permanent colostomy, is experiencing sharp pain in the upper-right part of the abdomen and ongoing diarrhea. Despite having scans and X-rays that ruled out major issues like a hernia, the discomfort persists, especially when sitting. The person is seeking advice from others who might have had similar experiences. Here are some insights and suggestions shared by others:

1. Many people have experienced similar right-sided abdominal pain without a clear medical explanation, so it's reassuring to know you're not alone.

2. Consider the possibility of gas or air build-up:
- Some have found that excess wind can cause similar pain. Reducing foods that produce gas and gradually changing your diet might help ease the symptoms.

3. Keep a detailed food-and-symptom log:
- Track what you eat before the pain episodes to identify any triggers. Foods that were fine before surgery might cause issues now.

4. Consider the possibility of gallstones:
- One person with a colostomy had the same type of pain, and an ultrasound revealed gallstones.

5. Review your medications:
- A large regimen of medications can sometimes contribute to gastric discomfort or gas. It might be worth discussing this with your physician.

6. Counteract the side effects of antibiotics on gut flora:
- Antibiotics can disrupt intestinal bacteria and worsen diarrhea. After each antibiotic dose, try eating probiotic foods with "Live and Active Cultures" like yogurt, kefir, sauerkraut, or kimchi to help replenish gut bacteria. Start with small amounts.
