I have been on Vytorin for about 4 years; was taking Crestor before that. In the last year, the tops of my feet have developed a burning feeling, and different parts of my feet have numbness at different times. I also got up 2 to 3 times per night to urinate. My core felt weak and my muscles ached. I read the comments on this forum and others regarding Vytorin side effects. I decided to quit taking this drug and informed my doctor of my choice. Vytorin got my cholesterol down to 137, but who cares. I'm relying on a sensible diet and Omega 3 to keep me going. The foot burning is still there after 3 weeks but it seems like its less than it was.
