Hi, I have got to get a knee operation next week and am really nervous.I hate hospitals and even had a panic attack when i had to see the consultant.I am going to the doctors to ask for sedatives for beforehand,do they work?,do they stop you from being hysterical and panicky?.Couldanyone also tell me what would be the best anesthetic ,local or general.the side effects with general are ot nice,but i would be awake during a local and could really panic.I would really appreciate your help.
