My husband started taking Zocor two months ago. He has always been very energetic and healthy. He is experiencing sore muscles, flue like symptoms, leg cramps, blurry vision, loss of concentration, pain in his heels and feet and is having trouble sleeping. He has severe hip pain and had x-rays taken but the results did not show anything wrong. After going to this website he is stopping the Zocor and seeing his Physician immediately.
