In fact, it is a frequently-occurring and common disease, and it is an important infection focus of anorectal. Anal sinusitis has the following obvious symptoms: 1, feeling of incomplete defecation: in the early stage of anal sinusitis, patients often feel incomplete defecation, accompanied by the feeling that foreign bodies are embedded in the anus and fall down. 2, pain: generally tearing pain or burning pain. Laceration pain is often accompanied by anal injury or inflammation spreading under the surface of anal canal, and the symptoms are aggravated when defecating.

Reflex pain: Anal sinusitis often has reflex-like pain, which can be reflected to the genitourinary region through the internal pudendal nerve and the third and fourth sacral nerves, to the sacrum and coccyx through the iliohypogastric nerve and the anal tail nerve, or to the lower limbs through the sciatic nerve.
