Oh MyAching Back

I've really done it this time.  I threw my back out yesterday.
We've got scaffolding up out the back... I have to bend down to clear it in order to access under the house where the washing machine is.
Whilst exiting this area yesterday, in a hurry, I bent down as usual and kind of twisted/turned as I went to stand upright and that's when it happened.  Seized up.  Very VERY painful.  It took all I had to get in the house.  I then crawled to the front room where I could do some stretching exercises.  That's what I usually do when my back is giving me trouble... Not this time.  I couldn't do a thing.
Rested the rest of the day with a hot water bottle on it.
I managed to get to the school to get Lloyd and his cousins.  Few steps, rest.  Breathe through the pain.  Repeat.  That was just getting to the car!
I spoke to a Physiotherapist (who has no appointments until Monday!!) who said just rest, keep warm, take pills.  When it's so acute, there's not much he'd be comfortable doing anyway.
Sadly, it's no different today so here I lie.
Lloyd and Greg are at rugby.  It's a sunshiny day and I had plans!!
And tomorrow I was to help serve food at the church lunch and make friends!
Sigh
