With respect, the comment in the bold, coloured text misunderstands what ice actually does to blood vessels and muscle tissue when placed on the body in a non-acute situation. People with CRPS don't have acute tissue trauma and when ice is used on the body it doesn't constrict blood vessels. It reduces pain, relaxes muscle and causes the blood vessels to relax and dilate. This is, for example, why ice massage is regularly used by physios and athletes.

I'm not prepared to get into some kind of battle of published medical authorities. *admin edit*

Everyone is welcome to (and should) do their own research and form their own views. I've said all I have to say on ice *admin edit*
