It's healing pain. Remember, you might have an incision in front, but the pouch was stapled (or stitched) to the rectal cuff, which is exactly where you're describing the pain. I had aching and pain in that area for probably a solid six weeks after step 2, and it was definitely worse on days when I was more active. It eventually tapered off.
A hole in the pouch is common, that's why everyone gets a pouchogram before takedown. They almost always heal on their own.
Good luck!
