Exparel is a wonderful -- but very expensive drug. It basically keeps you virtually pain free for about 72 hours. I usually use it when I anticipate pain due to muscle sutures, such as during a tummy tuck when I suture muscles together. When properly performed, gyne surgery does not touch the muscles at all -- so the pain after gyne should be minimal -- like a muscle burn only.
You should certainly inquire of your surgeon about Exparel -- but be prepared for a substantial cost for the product. That is why it is not used routinely.
