i suffered with chillblains for years through my teens and twenties. i got them on my hands as well as my feet and have even had to have a ring cut off because of the severe swelling.i regularly had days when i couldnt go out because my feet were too swollen to fit my shoes on.
i have found that as i've got older i have grown out of them mostly. the best relief i got was a course of tablets from the doctor, i think they were designed to help with my circulation.
i recomend pure wool socks to help keep your feet warm at all times. it is when your feet go from cold to hot that the pain occurs because the blood rushes into closed down veins and the blood vessels break and cause the painful swelling. its miserable , you have my sympathy.:sad:
