I'm not sure I understand exactly what you are experiencing. I can tell you that when I've been contaminated with dairy (one of my more severe allergies) my entire digestive tract becomes inflamed. That does leave stomach and intestines feeling like they are full, when really they are empty (because of vomiting and diarrhea). It does go away in about 24 hours. If you are chronically eating something you're allergic to, it might be a chronic condition. If you suspect food allergies, keep a food and symptom diary. That can help you and your health care provider identify the cause. Good luck.
