What are the symptoms of proctitis? How is it diagnosed?

Symptoms include constipation, feeling of fullness of the rectum or incomplete emptying, pain on the left side of the abdomen, passage of mucus through the rectum, bleeding from the rectum and rectal pain.

Doctors can diagnose Proctitis by looking inside the rectum with a Proctoscope or Sigmoidoscope. A small piece of tissue may be removed from the rectum and tested for bacteria, fungus or virus.
