Hey Daniella
I'm late coming to this thread but I wanted to share my experience with freezing feet. I live in Illinois and felt like I was walking on blocks of ice all last winter. I found the best thing was riding on my exercise bike about 30 minutes to get the circulation going. The effect lasts for about half the day. Of course, I don't know if your pain is too great for something like that. The other thing I did at night was soak my feet in a whirlpool footbath. That also helps. The main problem was walking outside and getting them chilled and then no way to warm up again at the office. Just some ideas for you.
