I've used the Zocor generic, Simvastatin for approximately 7 months with no problems. Suddenly, I began to experience pain in my muscles and joints. From one day to the next, my body was in excruciating pain especially my knee, I could barely get up from a seated position, and could barely lift my legs to walk. I told the doctor, I felt like a very old person. I am 53 and never had any problem with my knee. The doctor advised me to stop taking the pills. Now, all muscle pain is gone, but the knee pain is still huge problem. I am wondering if this will ever go away or will I be crippled for the rest of my life. Prior to this, my only illness was high blood pressure. I know that my recent problems are from taking Simvastatin.
