Zocor and severe pain

I took Zocor for 25 days when I suddenly had such pain at night in my upper arms that I couldn't raise my arms up at all. It's been 2 full weeks since I stopped taking Zocor, and every single night around 7 I develop severe pain somewhere in my body, usually in my hands, knees or feet. It's in a different place almost every night. Tonight it's in my left hand across the whole top of my hand, below the wrist. Can Zocor cause this kind of pain so long after stopping taking it? And I only took it for 25 days! Please help - this really hurts and I hope it will improve.

Except for having high cholesterol (310), I'm a 29 yr old healthy active female, very petite and weigh 98lbs. My mother has had a quadruple bypass and 4 stents at the age of 54, high cholesterol is just hereditary in my family. My doctor put me on 40 mg of zocor. The first week taking zocor I started feeling strange, a little soar here and there and very tired at times, also I have become very forgetful. It's been almost 2 months now and I have severe pain in my legs. First it was the right leg and now both legs, the pain starts at my lower back all the way down to my cav. I have a burning painful feeling sometimes numbing feeling, its driving me crazy!!!! I can't stand for too long cause I feel tons of pressure on my lower back pushing down my legs, It feels like my sciatic nerve. I went to my doctor and he said he is 95% sure that this is from the zocor medication, he told me to stop it right away. This is my first day without it, I know I need to do something to prevent what happen to my mother, I'm on a strict healthy diet, staying away from all fatty cholesterol filled foods, but there has to be a better way then taking statin drugs! If anyone has some ideas of what kind of alternative meds I can take, please help.
