What Causes Pain In My Toes?

I LIVE IN COLD BIG BEAR CA. I DO WEAR 2 PAIRS OF SOCKS ALMOST 24 HOURS. I'VE NOTICED MY 3 MIDDLE TOES REALLY ACHE AT NIGHT WHEN I'M IN BED. SO BAD IT WAKES ME UP. I WHIRL THE TOES TO MAKE THEM FEEL BETTER BUT THEY DO ACHE. I TOOK THE SOCKS OFF & WALK AROUND & THE PAIN GOES AWAY ABOUT 80%. WHAT CAUSES THIS? THANKS
