Andrina, you're going to just fine with this third surgery. Yes, it will take a while for your pouch to feel like normal. You will go through a time of adjustment where you think you are living in the bathroom, but it will get better. Make sure you begin eating thickening foods to help with the adjustment like potatoes, oatmeal, peanut butter, etc. (You may also want to start taking psyllium husks to add fiber and slow down the pouch.)
I didn't have wound care after any of my three surgeries. My surgeon just stitched it up and covered with paper strip tapes that fell off on their own. I did have a drain tube in after the second surgery that was pulled a week later.
The unknown is scarier than the actual procedure. Take a deep breath, you got this!
Praying this all goes well for you
