Has anyone ever just gotten chilblains on their heel?

For context, I’ve been dealing with chilblains since about 2023. I have EDS and Reynauds so this is certainly not my first rodeo, but this is the first time that I think I’ve ever gotten chilblains just on my heel. It’s not on my toes which I’m kind of surprised because I know I did let them get too cold this week along with my whole feet, but it’s just on my heel… That is if it’s chilblains, I think it is but it’s just so strange, so I was just wondering if this has happened to anybody else?

On a sidenote, it is absolutely crazy to think that I keep my house set to 77° and I can still get chilblains in 77 freaking degrees temperatures but I guess that’s the way it goes for people like us
