I recently completed Ironman CDA. About an hour into the bike I developed a pretty bad sideache - the type that you would normally expect during a run. It stayed with me for the following 5 hours on the bike and a few minutes into the run. Then I was finally able to get ride of it. Post race my stomache was actually tender to touch. Ever since IM I develop this same sideache every time that I run. I went out for 6 last night and 13 this morning- had it the whole run. Right now, just sitting here, my stomache is still tender. The pain is about two inches to the right of my belly button. I can't figure out what's causing it. Anyone out there had similar long lasting pain? I'm wondering if I pulled a muscle during IM from having the pain for 5 hours. Can anyone help???
