I was dx'd with livedo reticularis and it can go from pretty severe to mild - my case is moderate.

My skin will look normal, and with a shot of cold air I'll turn purple with white spots for exmple. And it could be that it's my hand that gets cold (reach into the freezer) and my lower legs will discolor. It's pretty weird.

No two people have exactly the same discoloration color/pattern etc, and it does go away.

It often goes along with Reynauds syndrome - I have that too.

Dx'd with both at the same time by a migraine specialist/neuro. my other neuros all agreed with the dxs. No meds were given, because they usually do channel/calcium blockers for serious cases, and mine's not that bad, plus I can't take that kind of med.

I use fish oil supps for other reasons, but that seems to really help with it.
