Painful Spams

I am experiencing painful spams in my lower colon.  I have experience this pain before and had a colonoscopy last year.  I was told that my colon was 100% covered with diverticulosis.  Recently I had some complications from the dentist office with a numbed tongue since Dec 28, 2009.  I've just recently started back eating solid foods and still haven't been really able to chew all of my food.  I have been trying to stay away from food with seeds and adding lots of fiber to my diet.  I have no idea what caused it to flair up this time.  The pain is so bad that I am taking vicodens.  At first I was constipated but now my stools are coming out real thin.  What do I need to do to relieve this pain?
