Nelie, I had a peg for 6 months and never had any noticeable pain. The insertion was pretty easy, just a little uncomfortable when they had me swallow the camera to allow them to see as they inserted the tube through the stomach wall. I stayed in the hospital, but that was because I had the peg inserted the morning of my second chemo treatment which was done with an overnight stay, so I was in the hospital anyway. That's one on the reasons I had it done along with the chemo.

The mask wasn't a big deal. You just have to ignore the use of it. I listened to music and prayed a lot at the time to divert my attention and to get caught up. I found I had a lot to pray about during this time.

I had two teeth extracted before rad and I have some additional dental things I need to take care of. So far, no big issues have developed except for a tooth on the other side which has crumpled a little around a filling. That will be part of a bridge I will need soon, though, so I'm not to concerned with it at the moment. Just makes eating a little more interesting. Hope all goes well for you.
