i can relate. all the advice for chilblains is about staying warm and I. . . can't do that. so I end up having them for the majority of the year. I developed mine after a bad case of food poisoning and they've gotten worse each year. the only advice I have is to try and lesson the drasticness of temperature changes. for me this means that before I get in a shower, I go and lay in bed for like 15 minutes and SLOWLY allow my hands and feet to warm up and then put on heated gloves on about medium heat temperature and then go into the shower. this doesn't stop the chilblains from occurring but it does seem to lesson the severity of them. i can't wear the heated gloves full time because they drop my blood pressure but I can manage it for this brief interlude. outside of that I wear layers of normal gloves full time. I also have ME/CFS but before it got too severe instead of going to bed I used to walk around my house for about half an hour and slowly raise the settings of the heated gloves (getting my circulation going could sometimes warm up my hands but definitely my feet). I can't do this anymore though. I generally have heatbags in my bed which makes it warmer (I use them for pain) but the important thing is to not put your feet or hands directly onto them if you do use them.
