As has been said. This situation needs to be dealt with before it happens, and it needs to be planned for.

Here's how my Doc works it.
I have a 'serious issue', I call him. He sends me to the ER, and, when I arrive, they're ready for me. If they need to converse with my doctor, (a Wonderful neurologist), They can and will, immediately! (I simply cannot, will not trust PM doctors!)
They can get him on the phone immediately, but, they usually know the deal, because he's already told them!

What a cool set up, huh?
But,
It's been almost a decade since I've needed to go to an ER, since my Doc has done one better!
He asks, that I 'save' some meds on 'good days', and that, I surely do!
So, that makes ME be responsible, For Break Through pain.
What a difference that makes, Too!

Hope all are well!

Love,
Pete
