Thanks. My right leg is doing strange things like swelling (when the other one is fine) and turning purple and such. It seems better when I sleep on my left side....it's just not always possible.
I'm pretty sure it's all good in terms of circulation. They just say that the 'best' circulation is on the left side. I sleep on my back as much as possible because that's how I can actually get any rest. Both of my sides end up killing my hips after a short time, so at this stage, if hanging upside down would actually result in sleep - I'd do it! :)
