Well, I don't know what to do. For the past couple days now every time I get home from a moderate ride (around 9-11 miles for 45 minutes to an hour) and I have severe cramps in my lower "gut". It's not my stomach, too low for that. It seems like it's my intestines. Anyone have similar problems and if so what did you do to alleviate the pains? And, if anyone knows, what causes this? Thanks guys.
