I'd like to get an idea about how many people experience back complications from sitting in full lotus for 1 hour plus on a regular basis. The internet is full of articles about how full lotus is great for your back/joints/credit but I suspect many of the people writing those articles don't actually sit in full lotus regularly and for long periods. So, of those of you who sit in full lotus for an hour plus a day, any chronic tightness or other maladies of note in the lower back?
A little bit of background behind this survey. I started sitting about 7 years ago, and have sat for a couple of hours daily until this February. During that time my back was constantly tight, I didn't attribute it to meditation at the time but when I stopped sitting regularly I noticed my back slowly corrected itself. I should pre-empt some comments about posture, my posture is good, and so is my cushion. In my case I think it has to do with scar tissue in my back from a fall when I was young but it could be more widespread, which is what I'm trying to find out. Your reports are greatly appreciated!
