I do have Raynaud’s, but this is something different. My hands are not hot or cold when this happens. It is just the look of my skin.
Here is a pic that I just took. Although my hand is not red, you can still tell that the skin is different. I can see a line at my wrist;not so obvious in pic. The skin is thick on the back of my hands and not like the rest of my EDS stretchy skin.
