So sorry about your broken foot.

I don't have RSD but I have had a lot of broken bones over the past 10 years. Considering that you don't have insurance, I thought I'd mention that I got great pain relief from ice. I broke 4 ribs, my pelvis, sacrum, ulna, radius .... and each time the pain responded much better to ice than to the Morphine I was given by the hospital doctor.

Give it a try, it certainly can't hurt. I hope that you feel better soon.
