Bill,
That's pretty common. Both the bit of leakage, and the "5 minutes of pain". My Dr. said there will be a little "friction". Yah, right.
I'll repeat JAM's statement. Keep it clean, and change the dressing. I worked down to a bandaid in about a week or so.
Congrads of getting the tube out. That was a big milestone for me. Keep at it.
Mike
