Hello...I have recently been diagnosed with IBS. I am an active 41 year old and marathon runner. I am not quite convinced as I do not have the classic symptoms. No D or C. My stools have been perfectly regular. However, I have had abdominal pain every day for nearly 15 months. Every day is the same. I wake up feeling well, but by about 2:00PM I have severe pain and bloating/preasure throughout my lower abdomen. I can't wear a belt or jeans. I wear pants with nearly 4 inch larger waist (I love the slight elastic extra waist band). The only thing that helps is lying down and taking a nap...sometimes only 15 minutes will help. I also have a sharp pain just under my left lower ribs...hurts to yawn and to take deep breaths...I had a chest x-ray for that and turned up negative.Some days are worse than others, but pain is every day. I had a colonoscopy and endoscopy...found nothing. I feel that I should be asking for other tests because I have no symptoms of irregular bowel movements. Does anyone have any suggestions? Thanks.
