I've done some reading, and I found an article following people who had not fused at one year. They gave them two hours a day with an external device to produce an electromagnetic field, and 68 % of these were fused by the next year.

It seems the process of fusion continues, and the trick is finding things that encourage the fusion.

I've asked my doctor to order me one of thsee, and he's agreed.

I'm back to feeling hopeful.

Also, the facet block worked, and the butt pain improved greatly. I had acupncture on friday, and got further games, and Feldenkrais on Saturday, adn after Feldenkrais, I sat for a couple of hours without pain. I'd not done that in a good 2 years.
