Whether or not the entire process of anoscopy is painful varies from person to person. Generally speaking, there will only be a slight swelling and pressure sensation. However, since the process is relatively short, taking only 3-5 minutes and only penetrating deeper into the rectum, the discomfort felt by the patient is relatively mild compared with that of colonoscopy. In some cases, tension during the examination causes the rectum to contract and clamp the tube, making it difficult to perform the examination and increasing the examination time, which may result in pain during the examination. If you are concerned about the pain sensation, you may consider painless anoscopy. Painless anoscopy is injected with an anesthetic agent with sleeping and pain-relieving effects before the examination, so that the patient will not experience the discomfort mentioned above if the examination is performed in sleep, and the depth of such anesthesia is not deep, and it only takes 20 to 30 minutes to recover after the examination, so that the patient can return home on his/her own.
