Good luck krm, I just had my surgery last week 10/4 and everyone told me 2-3 days later I did not look like I had major surgery. You'll be amaed at he results. I felt like walking as much as I did prior to surgery but don't doit! Remember your outside will heal faster than the inside and needs time to repair itself.
I got my catheter removed after 6 days and glad to be unteathered. Depending on age, my doctor will remove the catheter 7-10 days but was impressed with my healing after 3 days we decided to go from 9 days to 6 days for removal.
It's natural to be nervous you just went through a major decision making process now relax, get prepared, think about what you want to do before surgery and what you will do to keep your mind busy through recovery. Keep us posted on your journey.
