I am saying that every procedure and any kind of anesthetic has risks. Birthing a child in any kind of way is never risk free.
So if a spinal is a no no, then she'll have to choose an epi or full anesthetic which have equally undesirable side effects. Not just the spinal.
Have you had an elective cesarean after the emergency cesarean? If so, what pain relief did you go for after the anesthetist has had a good informative chat with you and told you everything you wanted and needed to know about all drugs on hand?
With the emergency cesarean, you don't get a lot of time to think and choose what you want. With an elective cesarean, the hospital will give you all the information you need, well before you have your cesarean.
I am sure this will be the case for the OP too if she decides to go that way.
