Not out of the woods yet with regard to events taking place in my lower back, but it looks like I may be able to avoid getting a jab to relax the muscles therein. I was delighted to find myself able to get myself moving and walking round the house upon waking this morning, having suspected I'd wake in the early hours to the kind of unbearable pain I suffered back in Madrid, and things have got better since then. It looks like something inside is mending.
I think the fact that this date is a particularly happy one in our domestic calendar has helped the healing process. Knowing that you've managed to get at least one thing right in your life casts a rosy glow on all its various aspects, even the painful ones.
