If your feeling of abdominal soreness and bloating
started shortly after the fall, then it will be worthwhile if you decided to see a doctor.
Knowing if you had no internal organ damage will be more helpful than not knowing what is going on inside. If a CT scan
could be done at least your mind will be free of worry.
Do not forget that your bloating could still be as a result of a gut disorder/dyspepsia
and that you will be required to get treatment for that and follow a proper diet. You may also consult with a gastroenterologist.
Hope this helps
