This is an enema, right? No pain. My husband just got out of surgery. Before the operation, he will have an enema twice. The first time, it was cold water. He said that once he poured it in, his stomach felt cold and itchy. The second time, he asked the nurse to use warm water and felt much more comfortable. It won't hurt. It won't be long before I want to go to the toilet, and the purpose of enema has been achieved:)
