could be an abscess or stricture. I had tons of mucous discharge between 2 and 3 and then it reduced but I ended up having tons of pain. Seems I had a stricture, so I ended up having to have a dilatation under anesthesia between step 2 and 3. Just be forwarned if your surgeon tries a little look and see in his office first. OMG.. that was the worst pain I ever had. After that failed office scope he scheduled the dilatation for 2 days later.
