Aghast

You may well look like that.

I've just had a very unpleasant experience at the hospital.

Actually, it wasn't as bad as I had been told it would be. The traumatologist stuck a very large needle into my hip and squirted some oil or some such, to lubricate the damaged joint and reduce the pain I have been suffering for so long.

It's a bit early to tell how effective it has been.

I wait with bated breath.
