Pain in feet

I have been taking Vytorin for about 9 months. Recently I have been having severe cramping and pain in my feet and toes at night, similar to a stabbing nerve pain. My knees are also hurting which has never happened before. I walk on a treadmill but it only seems to get worse. I thought I had plantar faciitis, but now am wondering if the pain could be related to the medication. Could this cause pain in the feet and toes?
