Under normal circumstances anal examination is not painful. Before doing the examination, the doctor puts on sterile gloves with paraffin oil applied on them, which has a lubricating effect. You can gently massage the anus and then slowly insert your finger, which is not painful. However, if you have a perianal disease, such as having an anal fissure, a more serious hemorrhoid, or an ulcer in the anus. Because the disease itself is painful, a more intense pain may occur if the examination is done. In other words, if the pain is in an acute attack, an anal examination is usually not done to avoid aggravating the disease. It is not too late to give experimental treatment and wait until the pain is basically relieved, then it is not too late to do an anal examination, or to do some non-invasive tests, which can also serve the same purpose.
