This topic is about someone experiencing persistent nausea and pain on the left side near their colostomy, despite an emergency room visit and a clear X-ray showing no blockage. They are feeling scared and are looking for advice from others who might have faced similar issues. Here are some helpful insights and advice shared by others:

1. Pain and nausea might have different causes.
- Pain on the left side could be due to a parastomal hernia or trapped gas. Pain from gas often eases once it passes, while hernia pain can be more constant.

2. For nausea that isn't directly related to the stoma:
- Domperidone can help with nausea and indigestion by promoting gastric emptying, but it has potential side effects on the liver, kidneys, and heart.
- Other prescription options include:
- Ondansetron, which is effective but may cause constipation.
- Promethazine, which is sedating and useful if rest is needed.
- Prochlorperazine, which is mild and suitable for mild nausea.

3. Over-the-counter and lifestyle tips:
- Try small, frequent meals, ginger, cold fluids, and bland foods, which are often helpful and low-risk.
- Stay well-hydrated, as dehydration can worsen nausea.
- For pain or cramping around the stoma, alternate between ibuprofen, acetaminophen, and naproxen as tolerated.

4. If pain seems related to slow bowel output:
- Drinking warm prune juice can stimulate bowel movement and relieve discomfort.

5. Medical follow-up:
- Since the ER ruled out obstruction but symptoms persist, it's important to schedule an appointment with a family doctor or a colorectal/stoma specialist for further evaluation, such as checking for a hernia or additional imaging and lab tests.

6. Keep a symptom diary:
- Track the timing of pain, nausea triggers, and output characteristics to help healthcare providers identify patterns and causes.
