### Patient: Doctor, I am having some issues with pain and swelling in the tissues surrounding my rectum. 
### Doctor: Based on your symptoms, it sounds like you may have a perirectal infection. In order to determine the extent of the infection, we will need to perform a rectal examination. Afterwards, we may need to manage the wound through wound care, and may also administer intravenous fluids to ensure proper hydration. Kidney function tests will also be necessary, as the kidneys can be affected by severe infections. Additionally, we will need to perform a complete physical skin exam, and may need to perform an incision and drainage procedure to help to alleviate the symptoms. Finally, we may conduct an X-ray computed tomography (CT) scan to fully assess the condition.
