This symptom is most likely due to gas, constipation or mild gastritis, especially since your USG 2 months ago was normal except fatty
liver.
Next Steps
Advice: - Increase water intake and fiber in diet
- Take light food and avoid oily/spicy items
- Start a mild laxative or fiber supplement for constipation

No need to repeat USG immediately.
