It goes so quick you won't have time to worry. I had a cs two years ago, scheduled. From the time they gave me the spinal to the time they were stapling me up, was 15 minutes. The spinal dod make me very nauseous but just say something and they will give you something in your IV that stops it immediately. You will feel tugging, pressure but it doesn't last long. You'll be fine.
I got a c section 7 years ago and the spinal wasn't bad the healing process for me was extremely tuff. However I felt a lot of pressure during the process but I was fine.
