Where are you going to be staying for the first few days after surgery? Will you have drains? If you have drains and you're planning to stay at home with your family, the will notice. You'll be walking around like a 100 year old for the first couple days as the drains in your armpits do not feel good, and you essentially have to end up walking around them. I had my operation on a thursday, and had them taken out on Monday. I woke up with the compression vest on and didn't take it off until I was at the doctor's on Monday morning to have the drains removed. Yes, I was smelly. But it was just not worth the aggravation of getting the thing on and off. I now wear the underarmor during the day and sleep with the vest on. During the day, I have to vest on my back porch airing out - I honestly haven't washed the thing yet. Gross, but whatever.
My doctor did not let me leave with a cab, I needed a 'friend', so I put on facebook - 'Anyone want to make $50 cash? you must have off today and have a car.' I had several bites and one facebook friend, not a close friend, was willing. When she picked me up, I said that I had to have a cyst removed but didn't want my family to worry about it so I kept it quiet, and she asked no questions past that - she didn't even take my $50 bucks!
You'll be stuck inside for a few days so you'll need to stock up on some food to have in the house and a couple bucks in case you decide to order something.
