I know this will probably sound as a stupid thing to aks for but...
Does any one of you knows a spell to change your own temperature?
My hands sometimes feel very cold and no matter how much I do to make them warm they don't and other times they are burning... I can put my hands beneath cold water for a while but when I take my hands from under the water they are as hot as before...
The temperature sometimes hurts so it's really inconvenient, sometimes I can't even hold my pen -_-''
I hope that someone can help
