I have been on Vytorin for about six months. I just recently started experiencing numbness/tingling from the waist down to my feet. I have also experienced it in my forearms and fingertips. Two days ago, I woke up and my face was tingly. My muscles are very week, and I have no energy. I stopped taking it two days ago, but haven't seen any improvement, yet. Hopefully, I'll see some soon. I am drinking lots of water to try to get it out of my system. I am done with statins.
