I have the same thing, sometimes more swollen than others. I think it is when stool is in the intestines and after it passes through, it goes down some. I do have a hernia, but I think I have had this problem for a long time now, so I don't think it is just the hernia problem. I also use a similar Hollister product, and it is soft and much better than the ones they give you to go home from the hospital with. Show your doctor and see what he says. Good luck, Joyce.
