I have been on Vytorin for several months. I had issues, but didn't think it was the drug, like tennis elbow. Now two days ago, I have had severe muscle pain from my lower back to the tops of my feet. I've had to take vicodin for the pain so I can sleep at night. I stopped taking Vytorin and only pray that the pain will go away. I have read many websites that say the pain may never go away due to damage to the muscles. I can't believe this. I am suppose to have surgery to have my ovaries removed due to pain in my pelvic region, now I am wondering if it's Vytorin causing the pain. I have also experienced headaches for days, blurred vision, severe sleepiness all day, painful hip joints, irritable to name a few.
