Hi, I've been working on implementing the steps for a couple of weeks now and feel like I'm starting to sense my position and stay in it more automatically. Some days my back has felt much better; other days I have had pain, perhaps because I'm trying to adjust to a different pillow, keeping my corset engaged, etc. However, sometimes at night when I'm stretchlying, different bones in my back or sacrum pop. I've been to a chiropractor off and on for years, so I thought perhaps my ligaments are stretched? If this is the case, is there a way to tighten them so that I don't pop so much? Thanks!
