I have had no fever and no lower abdominal pain other than some "rumbling" and sense of urgency when diarrhea occurs. The diarrhea since Wednesday has been not more than 2 or 3 times a day other than the nocturnal diarrhea. I was fine all day yesterday after only one morning episode and walked 18 holes of golf. Thought it was abating until I awoke at 2 am having soiled the bed. This is weird. Could a course of Flagyl be indicated if this does not resolved with the use of Immodium over the next few days.
