Just remembered that the pre-op nurses gave me something they called a nerve block. From what I heard it sounded allot like a epidural just without a lingering needle. I must say that it was more uncomfortable to get than an epidural. The must concentrate on a specific nerve. When they hit the right spot my left leg started twitching like it was being electrocuted. Post op I had a great amount of pain at the injection site but no other side effects since then. If it helped with the post op pain I would have HATED to experience it without it.
