Perianal abscess is an acute infectious disease of the local skin, mucosa, and sphincter around the anus, characterized by certain acute clinical symptoms, most commonly pain. The onset of a perianal abscess is generally sudden, occurring within one to three days. Due to the formation of a local pus cavity, intense pain is experienced along with the red, swollen, and hot skin in the affected area. The nature of the pain is often throbbing or pecking. If the infection worsens or is not actively treated, it may also cause systemic symptoms such as fever and chills due to the pain and infection. With repeated attacks over a long term, or if the patient's physical condition is poor, further symptoms like fatigue might occur. Acute episodes of perianal abscess require prompt surgical intervention.
