Myopathy has been estimated to occur in about 1 per 10,000 patients treated with statins . My own personal experience suggest that mild muscle aches and pains related to statins is more frequent.
High dose = higher risk
Higher doses of Statins are associated with increased risk of muscle and liver damage . The initial recommended dose gives the greatest reduction in LDL cholesterol , about a 27% reduction, subsequent doubling the dose results in an additional 7% reduction in LDL. This is called the rule of 7.
American J. of Cardiology 1997;80:106-107
For example 2 commonly used Statins
zocor Lipitor LDL Cholesterol % reduction
10 mg 5mg 27% reduction in LDL
20 mg 10 mg 34% reduction in LDL
40 mg 20 mg 41% reduction in LDL
80mg 40 mg 48% reduction in LDL
80 mg 55% reduction in LDL
There is great individual variation in the effect of statins but general you get the most bang for your buck with the initial starting dose , a 27% reduction in LDL cholesterol
The subsequent 7% reduction attained with each doubling of the dose comes with an increasing the risk of muscle and liver damage.
There is another option .
Reduce your fat intake
Reduce the Fat intake in your diet by 25% and lower your LDL cholesterol by 5% without the risk of muscle and liver damage

the Efficacy of intensive diet therapy alone or combined with lovastatin
"A reduction in calories from fat from 40 to 20% , a 50 % reduction generally leads to approximately a 20 % reduction in LDL and total cholesterol"

Comment on food
( little changes done over a long time work better than big changes done over a short time )
The Dean Ornish diet , 10% fat intake, mentioned above was a little to difficult for most people to manage long term. However his studies were some of the first to demonstrate the power of lowering fat intake in managing and correcting cholesterol problems.
Vegetarian diets some of recent ideas of the Mediterranean diet , Dash diet are a little easier to accomplish by gradually working them into our individual our life styles over time . You have plenty of time to make the changes , because managing cholesterol problems is a life time challenge and total reliance on a pill usually fails . See my comments on the Dash diet on May 19 post, The Dash diet my experience.
Have more fun
Spending you dollars on fruits, vegetables , whole grains and low fat dairy products is more fun than paying cardiologist and heart surgeons for their amazing skills.
The 5 % lowering of LDL cholesterol attained with a reduction in dietary fat intake is without risk and is not much different than the 7% reduction attained by doubling the statin dose with higher risk of complications. The primary benefit gained from your "Statin " is with the initial starting dose , a 27% average reduction in the LDL cholesterol and then save time , you don't have to read food content labels , by shopping in fruit and vegetable section of your grocery store.
Have fun , Be smart and eat your fruits and veggies
