Wow, how horrible is that. Not only having to deal with the pain, but the frustration of going through all the red tape. Plus it must be very scary for both of them!
Hope they get results fast. Can they go to their primary care doctor to get the meds to at least get him through the time before he sees his back doctor? Or can his back doctor call in a prescription?
The medical profession can be very frustrating and complicated here in the USA, I don't know how they work in Canada.
My thoughts and prayers are with them for a speedy recovery!
