e aThe flash drive is a medic alert device if I wasn't clear on that. I got mine from Amazon for about $25 several years ago. I've had 3 or 4 of them over several years and while I've gotten bad about wearing it I know that I really need to (I'm dangerously allergic to tetanus shots and because of my MAOI if I have to get one and then be treated for my allergy they have to be ready for emergency care when the allergy treatment interacts with my MAOI and makes my blood pressure skyrocket). I have asthma and it's also easier than choking out information when I'm having a bad attack. I can update whenever needed in just a few minutes and it has all my drs' information as well as my medical history, meds, and in theory I can add test results and xrays and things but I've never tried that.
