As to whether proctitis will cause discomfort in the rectum, it depends on the specific situation. If it is only mild proctitis, generally, it does not cause discomfort for the patient. However, if the proctitis is severe and accompanied by conditions such as rectal ulcers, rectal discomfort is likely to occur, and the patient may experience symptoms such as pain and a sense of urgency followed by incomplete defecation. In severe cases, fever may also occur. Once a patient develops proctitis, it is advised to promptly complete an electronic colonoscopy examination. If necessary, tissue should be taken for a pathological biopsy to rule out the possibility of malignant tumors in the rectum.
