Hi, for the past 5 months, every so often, I get dizzy spells about 5 or 10 min. before I have a bowl movement, it doesn t happen ever time but about once a week or once in 2 week span. I had blood in my stool once about 3 months ago and now it happened today again. I booked a appointment with my doctor, but I cant see him until Monday. Is this something I should do something sooner about. Thank you.
