Local anaesthetics suck. When I was in my huge near death car wreck, one of my injuries was a shattered elbow. They didn't worry about the elbow for the first two weeks I was in ICU, they were just trying to make sure I kept sucking air into my collapsed lungs. Finally, a doctor noticed that my elbow was broken and since it appeared that I was going to live after all, they figured they'd better go ahead and set it. But they didn't want to give me general anaesthetic for what was going to be a very complex surgical procedure (the elbow was broken in 7 places or something). They figured my lungs would give out again if they did. So they assured me all would be well with just a local. HAH! I have never experienced such horrible pain in my life! They'd have done better to do like they did in the old Westerns and let me chug a bottle of Jack Daniels beforehand.
