As of now, I'm pretty much cured of my back pain and sciatica problems of the past several months, and about time too. I'm not exactly performing back flips here - as a matter of fact, I'm still taking painkillers - but I can do 'normal' stuff like go shopping in town or meet with friends in the West End or even go to parties without suffering undue stress. I'm still holding back a little bit on running out to get a new day job, since I've learned the hard way not to rush things. Perhaps in the next couple of weeks I can start looking properly.
The nicest thing is literally not lying around all day on my back propped up on cushions. To this end I bought a new 'office' type chair for my return to sitting-up writing and browsing in a sale for only thirty quid; it's not exactly an Aeron super-duper chair, but right now my spine loves me for it.
