I've been sitting on my foot and it went numb, but I looked at it just now and my toes are a blacky purple colour, I think that's bad 
It's almost normal now, but it was slightly scary

oh no, that means your foot will drop off
it should really, but it's fine now, and I was only sitting on it for 10ish minutes
and I don't leave that close to the artic!
