This is a folding four-page card and is small enough to fit in a wallet or purse. Perhaps keep some on the dashboard of the car, in your desk at work, or in your briefcase or handbag. It is a quick way to explain the disease to people. The cards are credit card size.
The card is useful if you get challenged over using a disabled parking bay, or just want to explain your situation to someone you meet. The blue section on front and back has a short explanation of McArdle Disease. The white section on the back has some pointers on the sort of assistance that you might need.
On the inside the card has guidance on what to do in event of an episode of rhabdomyolysis. It has a brief note for emergency doctors with a space for you to write in a name and/or phone number of a doctor who should be contacted in the event of an emergency.
