6 days dpo, bowel issues

Hey guys! I'm a week past operation tomorrow and I've really been struggling. Right after I eat, my stomach cramps up horribly. It's like I can feel the food landing heavily as I begin to digest it. Every time I have to make a bowel movement, my stomach cramps up horribly. It is MISERABLE! I couldn't immediately go to the restroom this morning as they were both occupied and I was literally moaning, clenching at my stomach and calling out in pain... I am also having a lot of pain on my actual booty hole. I've never had a hemorrhoid but I imagine this is what it feels like? Almost like it's swollen or something and just very tender when I sit on the toilet, cough etc. Actually passing bowel movements is excruciating. It feels as if my entire bowels are swollen or something so the entire digestion process is really painful. I have not been constipated during all of this and have not been straining at all. Is this normal?
