Winter weather causing Stifness/Joint Pain?

[mirkocrocop]

For the past few years I have been starting to notice that as soon as Winter starts here on the East Coast my body becomes really stiff and joints begin to hurt. I also feel more susceptible to injuries and muscle cramps in the Winter. Is there a logical explanation for this? Has anyone else experienced this? During the Summer my body feels really "lubed up" and less stiff.

My back feels the same way where i had surgery last year and my left knee too. I still have pain during summer but winter is a mofo and everytime the weather changes i feel like garbage
