PANTS ON FIRE!!!

I've totally done my back in. It started with doing the stall a couple of weeks ago and has been getting progressively worse to the point that I now can't move, or even breathe, without yelping loudly in pain. Managed to get myself to the Docs this afternoon (and blipped this on my extremely painfully slowly walk back), it's apparently a muscle thats seized so I have to take the pills and try to stretch it when it becomes bearable. Ouch.
