I’ve had Raynauds since I was a teenager, but I got chillblains for the first time last winter. This winter, they are worse than last year. I’ve had chillblains on at least one toe for the past three weeks. As soon as they clear up, I get more in a different place. Does anyone have any suggestions for how to prevent them or treat them? They go away on their own in about a week or so, but they’re very painful in the meantime.
