Hi Sue,
I have had a flap as well. The skin graph is not too bad. When I had my first one in 06 it was painful but the way they do it now really isn't that bad. I can totally understand the roller coaster of starting to feel better only to have another surgery. Not all mine were because it returned but they were not the most fun either. Glad you found us to be able to vent and get support and information. Also soooo glad that you had a good time on your vacations. Those are so important to help with the roller coaster of it all.
Not sure about your flap but with most flaps the hair that was on your arm will be in your mouth. It's kind of weird but they can take care of it later. Keep positive about the flap and don't worry about the statistics.
