Distending (swelling) is another symptom of IBS. Nobody has a desire to experience bloating feeling. Once you have diarrhea or the opposite problem, be sure to face bloating as they are interrelated symptoms. As the excess gas gathers in the area around the bowel, swelling appears. Women suffer more than men because of the changes in hormonal levels.
Pain in the back might be another clue that you have IBS. Well, in some cases, the reason for a backache to appear are the abrupt body movements or damaged joints/nerves. IBS cannot be confused with rheumatism as all other symptoms must be present. It is important to see the doctor and share the symptoms to understand the true source of a problem.
