Chilblains

I'm 99% sure I'm suffering from chilblains. I've never had this issue in my life, but suddenly for the past two weeks my toes have been INSANELY itchy, slightly swollen and sore at night. In the day less so, but at night it's so hard to ignore the itchy pains.

I'm going to get some cream to put on, do you guys have any suggestions for treatments too? Would putting on an extra pair of socks at night help?
