It works just like it would for anyone else, but it also causes a huge shift in electrolytes because of the "fight or flight" response and that is what makes us very stiff. Be sure to wear Medic Alert jewelry and put in your file online that epinephrine can exacerbate myotonia.
Will do. So it's probably not life-threatening, then, which is cool! If it just causes pain, well, pain's better than dying from anaphylactic shock. :)
I actually just ordered my medic alert bracelet because I hadn't been aware of the cardiac arrest danger in addition to the MH danger. That was the tipping point for me! The official Medic Alert stuff doesn't have room for all my diagnoses--exercise-induced anaphylaxis is kinda long. So I got an unofficial one and will be carrying a wallet card, too, with better info.
