Getting serious chills from spicy, hot food?!

I've noticed that when I eat hot wings that are really spicy, I get a serious case of the freezing-cold chills; it's the exact same feeling as if I've had wet clothes on all day. Feels like hypothermia (at least, I imagine it does :p).

I've searched all over Y!A and the rest of the 'net in hopes of finding something out, but I can't seem to find others with this problem? What could be wrong here; is it anything I need to watch out for or could it be a normal reaction?
