I tend to think if there is a clear cut reason for surgery, and c ribs fill the bill for that, putting it off for too long could create more problems than just biting the bullet and having them removed.
Think of the internal rubbing and crowding, that could be causing scar tissue just from the irritation.

If the being put out really bothers you, ask about the possibility of some pre surgical anxiety meds, if you decide to go for surgery.

You'll know when you are ready to decide.
