Six months after surgery for a perianal abscess, if there is local pain at the wound site, it is first necessary to rule out the presence of local infection and recurrence. To differentiate between infection and recurrence, it is necessary to conduct a digital rectal examination and a perianal ultrasound to confirm the diagnosis.

If infection and recurrence are ruled out, consider the possibility that the pain may be due to contraction and softening of the scar tissue at the site of the perianal abscess surgery, leading to painful stinging at the wound. Local application of anti-inflammatory ointments or gels can be used to treat the inflammation. If the pain or discomfort is severe, Chinese herbal washes or dilute salt water can be used for fumigation and hot compresses on the local scar.
