Anytime you have surgery it is a big deal. Every time you have surgery there are risks involved. Every time you get anesthesia there are risks involved. So anytime you choose to have “elective” surgery instead of necessary surgery you really should think it out seriously and decide if it so necessary that it would truly make a difference in your life and then rethink it one more time.
Having said that, if the issue is making you so unhappy that it is affecting your life and correcting the situation is something that would seriously make a big difference, and I truly mean make a seriously big difference in your self-esteem and self-confidence then you should discuss it with someone you truly trust will guide you in the right direction. By that I don’t mean your best friend.
