My stomach swells up like its inflammed and hurts. its like that for a couple days then stops. its always coming n going. could it b ibs r sumtin else?

Could be...: Ibs or it could be simple gas. Look to your diet; is there something you eat right before these episodes occur (dairy products, beans, etc.)? Are you having normal bowel movements? Does a bowel movement make the pain and bloating go away? If the symptoms persist, the best thing is for you to be completely evaluated by your doctor.
