Reflex pain: the occurrence of enteritis is generally reflex-like pain. When examining the anus, you will find that the anal sinus and anal nipple are congested and swollen. It generally affects neighboring organs and so on. It 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 anorectal nerves, or to the lower limbs through the sciatic nerve.
The feeling of incomplete defecation: that is, it is often said in medicine that you feel heavy after being anxious. Patients will feel comfortable, but they can't exhaust when they go to the toilet. Always going back and forth. This is because the anal canal is rich in nerve fibers, both of which are unmyelinated nerve fibers. At the same time, there are myelinated nerve fibers and more ganglia, forming an accessory sensory organ. Therefore, in the early stage of enteritis and anal papillitis, patients often have a feeling of endless defecation, accompanied by the feeling that foreign bodies are embedded in the anus and falling to the ground.
Pain: Pain is also the most common symptom of enteritis. It will aggravate some pain around the anus when defecating. It hurts like something is tearing, and it hurts. If the external anal sphincter is stimulated, the anal pain will be more severe. So patients are generally afraid of defecation.
