blood and bloody mucus in stool and gas pains....

Hey everyone.  Almost for two years now, I've been having bloody stools (not always) and painful bowl movements and painful gas.  The blood is in my stools and in the toilet/on the paper.  At first my family doctor said it was nothing and it would go away.  Then she thought it was a fissure.  She perscribed me several medications and ointments to help it go away.  Which it didn't.  My doctor doesn't exactly listen to her patients very well.. Thats besides my point.  A few months ago I had a colonoscopy done, in which a polyp was removed.  I haven't heard anything back yet (probably because my doctorss office ***** at calling people..)  Anyways, my symptoms are still occurring.  So now I'm trying to do some of my own research to find out what is going on.  Any help?

I should also add that I freequently feel I have to make a bowel movement.  Sometimes right after I eat.  Its not diahrea, but it is soft.
