back to the back

Normally, thanks to much manipulation of my skull and spine by my osteopath, my back is pretty stable. The last couple of days it's been annoying me. I've had a few spasms in the muscles in my back and although my left thigh is always numb, now I get random cold spots and fuzzy patches and it feels like things are touching me when they aren't, and I can't feel things when they are. It's not exactly painful, just really irritating.

And I've been on the NHS waiting list for 16 months now....
