I do not want to take away from the RSD bracelets, but an RSD friend gave me the coolest Christmas present. It is an emergency bracelet that is a computer chip and can be plugged into any USB port. It is THE COOLEST. The program is easy to use and easy to update after DR. visits ,Med changes etc. It is also water proof and can be taken on/ of much easier that my old traditional bracelet. They are not expensive and I highly recommend it. Fondly-Carol
