Zocor and pain medicine

I don't remember when I started taking Zocor - I think it was late 1990's. Recently I've been having pins and needles in my legs, arms and other parts of my body. Doctor did an EMG and it came back normal. Blood tests were also normal. He's now sending me to a neurologist. I researched Zocor and found that it can cause nerve damage which is what my doctor said I probably have. The research said that it starts in the feet then travels to the rest of the body. In 1999 I went to the doctor with pins and needles in the feet and he diagnosed it as arthritis and gave me quinine. I was in a car accident in 2001 and have been on pain medicine since then which was covering up the pain. The pain sometimes has me using a cane.
