So yesterday afternoon I was doing my secondary run of the day which was an easy 4 miles. At about three miles I got the worst side stitch I have probably ever gotten. I have had some occasional stitches during hard runs but nothing like this and especially nothing like this in probably 5 years. The thing is when I ran this morning I again got the same stitch and at the end of my run it was just as bad. I mean tough to even walk type stitch. And it of course returned at the end of my secondary run this afternoon. Just wondering if anyone has any explanation as to why this cramp keeps returning? Thanks for any help.
