For the last week or two i habe experianced excess gas and a pressure around the colon. i have no other symptons. bowel movements are normal. help?

Are U sure it's gas?: Many report a sense of gasiness, bloating, pressure, abdominal fullness. This may (or not) originate in gut, & may (or not) be disease-related. Some are sensitive to gut distension, have bacterial overgrowth, have altered gut motility or inflammation. It's best to get checked. Also, keep a symptom diary, consider bifidobacter probiotics, start food elimination trials, avoid artificial sweeteners.
