Millions of Americans take statins to lower their cholesterol. Common side effects from these drugs include muscle pain and soreness. Usually those effects are just annoying, but some patients suffer muscle weakness as well, especially around the haunches, which can be debilitating. My findings? The side effects don't always go away when you stop taking the pills. Orthopedists see this all the time and say it is a concern, but most docs downplay it. Be vigilant if you're starting a statin regimen, and talk to your doctor about switching or discontinuing drugs immediately if you develop severe or disabling symptoms.
