Why is my stomach always hard bloated and sore ? could this be ibs

Yes, but...: When you say "swelling" are you relating your abdominal circumference to feelings of distension, fluid retention, constipation, overeating, or do you feel pregnant? Hard to answer your question without further information and clarity. Over what period of time have you noted the swelling--minutes or months, and what are your underlying medical problems (alcohol, liver disease, gut problems...)?
