My husband has MS and as I posted before he will be in an electric wheelchair, he can and will use his cane for short periods when possible. because he has a severe lack of balance and of course fatique. some of you may understand that the heat and sun cause all MS symtoms to be worse. So what I wondered was how much info does need to be put on the card. I have to admit I knew nothing about MS till he had was DX with it. and realise that most people (even some dr.s) know very little. So would it be important to have it on the card that he cant be left sitting in the sun and heat and/or anything else that should be included info that you can suggest?
