Well, to me everything adds up to feet, it's my experience, and my yoga teacher is really big on the idea that if the foundation is misaligned, nothing else can be. So I'm a little obsessed. It does seem like sitting is part of your issue, though if soft chairs are easier on you than hard ones, that's very different from my nerve compression and also from any of my clients' with sciatica. Soft chairs are about the worst for me, because in a soft chair it's impossible to level the sitbones, keep the lumbar curve from reversing, or keep the pelvis from tilting back.
Anyway ... if you can spare an hour, check out this yoga video. It's a subscription site, but you can get a 15 day free trial and cancel if you don't want to subscribe. This is all about the feet, which I try to be pretty good about anyway, but to just take the time to really focus on them is super beneficial and WAY more strenuous than what it looks like. I'm sore all the way up into my hips when I do this video, which is exactly how that works, and it makes my whole body feel soooooo good. http://www.yogaglo.com/online-class-...oundation.html
