First off - no it doesn't (well for a little bit) but it will return to normal.
Second off you are better with natual birth than a c-section, why would you opt. For surgery (unless it is needed, all for that of course!). Natual child birth does not mean the same thing as it did years ago. You have options, one I strongly recommend is an epideral(i know I spelled that wrong). If you are scared, call a local hospital and talk to one of the rn's on the labor and delivery floor. They will be willing to answer any of your questions.

you are a lot less alone than you think.
