How fantastic to have clear results and no further treatment.
Have a wonderful Christmas and take it easy. Someone told me to rest in the day if I need to and it's been excellent advice.
I think it's easier to be open about the scar. That feeling of awkwardness goes away quickly when it's something that's shared. I am a very private person and two weeks on and it's ok. My husband comes to my checkups with me and likes to know what's happening.
Take care and enjoy Christmas with your family.
