On June 1st I exercised for the first time in about 6 months. I ran and walked on the treadmill for about 40 minutes. The next day I was really sore (especially my abs.), of course, but my IBS was also really bad throughout the day, which isn't normal in my case. I had a stomach ache all day and had to rush to the restroom after I ate & I hadn't eaten anything that would usually trigger that. Yesterday my IBS was still pretty bad and today i'm not feeling much better. Do you think it was the exercise that could have caused this?
