Proctitis is an inflammation of the anus and the lining of the rectum, affecting only the last 6 inches of the rectum. Signs and symptoms
A common symptom is a continual urge to have a bowel movement—the rectum could feel full or have constipation. Another is tenderness and mild irritation in the rectum and anal region. A serious symptom is pus and blood in the discharge, accompanied by cramps and pain during the bowel movement. If there is severe bleeding, anemia can result, showing symptoms such as pale skin, irritability, weakness, dizziness, brittle nails, and shortness of breath.Symptoms are ineffectual straining to empty the bowels, diarrhea, rectal bleeding and possible discharge, a feeling of not having adequately emptied the bowels, involuntary spasms and cramping during bowel movements, left-sided abdominal pain, passage of mucus through the rectum, and anorectal pain. Sexually transmitted proctitis
Gonorrhea (Gonococcal proctitis)

This is the most common cause. Strongly associated with anal intercourse. Symptoms include soreness, itching, bloody or pus-like discharge, or diarrhea. Other rectal problems that may be present are anal warts, anal tears, fistulas, and hemorrhoids.Chlamydia (chlamydia proctitis)

Accounts for twenty percent of cases. People may show no symptoms, mild symptoms, or severe symptoms. Mild symptoms include rectal pain with bowel movements, rectal discharge, and cramping. With severe cases, people may have discharge containing blood or pus, severe rectal pain, and diarrhea. Some people have rectal strictures, a narrowing of the rectal passageway.
Other treatments may include mesalamine suppositories, vitamin E, hyperbaric oxygen, or short chain fatty acid enemas; however these treatments are only supported by observational or anecdotal evidence. See also
