Two days ago I had diarrhea and needed to get on a flight so I took two pepto bismol pills. I had crazy constipation this morning--so hard I was literally trying to stick my finger in my anus and grab out the poop. My husband got me miralax [I had four doses] and an enema from the pharmacy, and that worked right away with a huge, still hard, BM. This was seven hours ago and my anus is still so sore that it hurts to walk normally. Now I feel like I need to go diarrea, but when I try to push, even gently, it burns and hurts so much and I am holding it in. Is this normal after an enema?
