Thank you for the link, the information is very helpful.

I also have Livedo Reticularis, and combined with the Erythromelalgia I guess whatever underlying autoimmune issue I have has to be neurovascular, which maybe narrows it down a bit but I don't know.

I've also been experiencing higher heart rates lately, even when resting (low 100s), and pretty bad insomnia.

It's been a few years since I had tests so I'm currently trying to go to the doctor and at least get a few blood tests done, confirm rule outs at least. But I currently live in a country where I do not speak the language so I'm trying to figure as much out by myself as I can.
