Medical instruments never bothered me, both because I was exposed to them myself and because I was raised around them, alongside their applications in animals and people alike. Of course I am not one to desire to be stuck, poked, prodded or bothered, but I can at least admit they are effectively a non-issue. I do not believe I have had a bad experience with medicine, other than the obvious like incompetent technicians or prolonged hours spent waiting or days to weeks for an appointment.
