A: You should inquire before the block, whether it is okay to drive home afterwards. With lumbar sympathetic blocks, you can never drive home afterwards. Generally when you have your first stellate or intravenous regional block, you should make arrangements to be driven home afterwards. If you are being treated for complex regional pain syndrome or reflex sympathetic dystrophy, the main purpose of the block is to enable you to have physiotherapy. You should resume your physiotherapy the same day or the next day.
