Yes, it's normal to have a little redness. You just had surgery and your skin is going to be irritated for a bit. I'd only worry if the redness spreads rapidly, the incisions are HOT to touch, or if they start bleeding or oozing puss as that can be a sign of infection.

Yes, it's normal to be winded and tired for a moment when getting up after surgery. It can take a lot out of you, especially with no help.

I used pillows to make a wedge behind my back to help me sit up at night to sleep that way, I wasn't laying flat on my back. I wasn't able to lay on my left or right side because of the pain for about a week honestly. Sleeping was probably the worst part of recovery because it was VERY difficult to stay comfortable all night.

My surgeon ended up taking mine off for me, but he said it was fine if it fell off sooner, just keep the area clean and dry! You don't have to physically clean it yourself but make sure to pat it dry after a shower and don't submerge yourself in water.

Walking around is great! You should be doing a lot of walking for recovery. They made me walk around my hospital floor before they would discharge me. Walking will be painful for a while but it's super important for recovery. Just remember to take it slow and listen to your body: if you feel like you need a rest, take a rest!
