I am unsure if my symptoms are indeed IBS. My symptoms are a dull ache which worsens with exercise (esp. running) on the right side (about the area of the descending colon?). The pain is accompanined by constipation. The pain has been pretty consistent this time for about a week or 10 days. I have had bouts of these symptoms two other times in the past 5 years - both, I believe, related to stress. The really unfortunate thing is that runnig is a big stress-reliever for me, and that is what seems to exacerbate the pain most - to the point of ending my run 10 minutes after I start - which leaves me even more stressed and frustrated! I intend to call my dr. in the am, but probably will not get an appt. for weeks. Any advuce on what I might be able to do in the meantime to relieve some of the pain?
