Hello @pga17, so glad you found this Mayo Clinic Connect group before your surgery.
I posted something you may find interesting.
WARNING! It's looonnngg! But full of good information.
I have posted before that I had like seven pillows in bed with me.
One for each arm. One for my head. One for my feet. One to hold on to. I guess that's really five pillows. But still...they were so comforting.

I went to TJ MAXX and got a two-pack of lounge bras for after surgery. These were so easy to just step into and pull up. It's not easy using your arms right after surgery. Trying to hook a bra is not impossible...but the lounge bras were such a great thing.
You do not want underwire anywhere near your chest wound! The bras were soft and felt like a gentle hug.

Before we left for Rochester, my guy got a La-Z Boy recliner that was electric with a remote.
I used it mostly because he was so wonderful to buy my an electric chair. It was nice, but I would have been fine without it as well.

You will be amazed at what your body will be able to do! It just knows.
Sure, you're gonna be sore for several weeks, but I promise...each day gets a little bit better.
Where is your surgery being performed?
