I Am 17 Years Old And My 2nd And 3rd

I am 17 years old and my 2nd and 3rd toe on both of my feet get itchy, red/ purple, swollen, and extremely sensitive when they are warm. Whenever I wear my boots at school this happens, when I sleep at night and my feet are under my covers this happens, when I have been wearing socks for a while, basically whenever my feet get warm. I went to the doctors about 2 years ago and they told me it was athletes foot so they gave me some cream to put on my toes but it never worked. I have looked up my symptoms and the best thing I found was Chilblains but from what I understood Chilblains happens when your feet are cold but mine happens when my feet are warm so I was wondering if you could help me figure out what is wrong. I went to the doctors again yesterday and he told me that my circulation in both feet was good so he's not sure what it could be so he wants to send me to me a specialist but he said that could take a while. So please let me know if you have an idea of what could be wrong.
