In infants, the abscess often appears as a swollen, red, tender lump at the edge of the anus. The infant may be fussy from discomfort, but there are generally no other symptoms.
Diagnosis & Tests
A rectal examination may confirm that you have an anorectal abscess. A proctosigmoidoscopy may be done to rule out other diseases.
