Anal Fistula: Symptoms
What are the symptoms of an anal fistula?
Ongoing pain, swelling, and tenderness are symptoms of both anal abscesses and fistulas. You may also experience drainage of pus and fluid from the abscess, which can cause irritation and itching on the skin around the anus. Other symptoms include fever, chills, fatigue or weakness.
How is it diagnosed?
A physician may be able to diagnose an anal fistula by physically examining the area surrounding the anus. However, if external signs, such as an opening in the skin, are missing, then an internal exam will be necessary. An instrument called an anoscope is used to inspect the anal canal and rectum for indications of an abscess or other inflammation.
