@kfhoz thanks for the response! I watched that video this morning ☹️ I did the same calculation as you - same result.

The appointment with my specialist has been moved forward to Wednesday afternoon 🙏

So very quickly in the last couple days I’ve lost strength and stability. I was foolish to do a short drive on Saturday when I wasn’t feeling physically strong.

Now I’m just doing regular slow walks and lying down as soon as there’s pressure on my spine. Not driving.
