I have been told I have ibs by my gp. I take peppermint capsules as needed and do help. Does anyone else experience this sense of bubbles in the rectum? I find it really annoying and accompanied sometimes with abdominal discomfort. What do you do to manage it. Sometimes it's without passing wind. Sometimes a short while after. I also experience what seem to be Large balls of gas that suddenly move out to the rectum but does not exit sometimes.I'm not intolerant to anything in milk. I also experience back ache and groin pain sometimes. Useally the symptoms pass quickly but useally in the morning. I can sometimes also hear loud bowl noises and feel gas bubbles moving around stomach. Also slight aching sensation Left side. Upper right sometimes. Sometimes before a bowl movement I have cramping feeling up the rectum. Thanks for advice.
