yes its happened with me also,last time when I went for medical treatment they ask me to ist renew my health card so I have to renew it and later get treatment.I agree that we should ready our documents but problem with health cards they are just renewing it and the expiry date is remaine same.I think there must be a way to check the validity of the card and if some one have any adea how to check the validity of the card please let me know. Thanks!!
