What are the symptoms of anal canal inflammation?

The symptoms of anal canal inflammation vary and mainly include: 1. Persistent pain: Patients often experience persistent throbbing pain in the anal area due to long-term irritation from feces. The pain is typically described as a burning sensation, which can affect walking and sitting. 2. Itching and moisture: Poor bowel habits and lifestyle practices may worsen the inflammation, causing local redness, swelling, moisture, and itching around the anus. 3. Swelling and abnormal defecation: Inflammatory irritation may cause edema of the tissues surrounding the anal canal, leading to a sensation of swelling. In severe cases, it may result in difficulty or abnormalities in defecation. 4. Other symptoms: Some patients may also experience additional symptoms such as constipation, bleeding after defecation, and a feeling of rectal fullness.
