                        I reacted very badly (felt like I was goiong to pass out) to a shot of novacaine prior to having a tooth filled.  I'm now experiencing anxiety even thinking about the next time I have to have a dental precedure requiring novacaine.  Has anyone experienced this and do you know why?
