Hello - I have mottled skin that started on my feet and moved up my legs, and now it's pretty much everywhere. Also, I have this weird sweating that seems to be associated with it. I get a strange sensation all over, like a twinge - it's hard to describe. I have toenail fungus and athlete's foot - don't know if this is related. But it seems like I have some sort of infection or fungus or something, all over...
