I forgot to answer someone's question about how my back is better. Well, my posture didn't used to be nearly as straight as it is now, so my mid-back got some strength in it. That was very helpful. I figure my posture will completely straighten up one day, but it's pretty decent now, thankfully.
My lower back goes back and forth, though. It's a digestive problem where a bunch of shame is buried that I'm trying to get at. I've gotten at some really important chunks of it lately, but there's still tons to go. I received an extra-large helping of shame from my mother, and some from my father, too. So I would expect it to take quite a while to integrate. Michael Brown was 7 years into his emotional work when he did a talk and said, "If I can't finish my emotional work, what hope is there for you?" That's a pretty arrogant statement, actually, because it presupposes that he's smarter and more emotionally intelligent than everyone else trying to learn his method. I don't think he realized that when he said it. A lot of people don't have the walls he has, so it'll actually be easier for those people to "finish" their emotional work more quickly. I don't know that anyone completely finishes their emotional work, but if anyone did, it may have been Brother Lawrence...maybe. That's a good book, by the way. Have to disregard all of the religious terminology and practice, but that's rarely mentioned in the book, and not really touted as the way to achieve connection with self and God. But I don't think Brother Lawrence fully made it...though he was close in many ways. Anyway, I got off track...I meant to say that Michael Brown never finished his emotional work, oddly enough. That's why his father issues come across blatantly in his books and that arrogance that a lot of people see in him. My personality type is fairly similar to his, so I have a particularly difficult path to take to integrate everything. I think a lot of people who create methods of healing usually have a rough road, because they need to be well trained at it. The more one has to deal with, the better they are at teaching others out of experience. Luckily, I worked through the arrogance at some point, so I realize now that there's very little we know for certain in this lif, and as a result, I can't bring myself to say I know anything for sure, save for a very few little things, such as we exist.
So, all of that to say, just because I still have ask problems doesn't mean you'll have back problems just as long.

Might be much much quicker for you...or maybe longer. No one knows. But the real key is becoming happy with the back pain so that it doesn't matter if it goes away or not. That's what I encourage. I'm much more accepting of my ailments now than I used to be, and that's really good progress. It makes like a lot more enjoyable.
