Researchers compared two groups of similar people enrolled in military health insurance and found those taking a statin were about 10 percent more likely to have muscle pain, sprains or strains.
Past studies have tied the popular cholesterol drugs to muscle weakness as well as the rare muscle-wasting disease rhabdomyolysis.
The new study expands on those findings and suggests the muscle-related side effects of statins might be broader, researchers said. However, they don't prove statins caused the pain and injuries seen among some patients.
