My Reynauld's would cause color change, from natural to red to white/clear when exposed to cold and this was a painful process. When heat was applied to reverse the symtoms I could watch the red color return to the clear translucent extremities., then the natural color returned.
At night I needed a heating pad to warm my feet, but once warm I could turn off the pad and here's the difference between my symtoms and yours, my feet never turned fire red and swell when they were hot.
As I have brought up, my lifetime of dealing with Reynauld's is almost forgotton. I've been taking CQ 10 for about 4 years. About 2 years ago I noticed I no longer needed to wear gloves just to handle cold wet produce in the grocery store or require my heating pad for my feet at night. I can wear flip flops most of the year. CQ 10 is only reported to work if you have had Renauld's all your life, it doesn't help if it is a side affect of a disease.
Also 3 years ago I cut out processed sugar, that lowered my internal inflamation and perhaps that helped too.
