Here are 15 evidence-based points:
Muscle aches can occur. Some people develop unexplained muscle soreness or discomfort.
Muscle weakness can be important. New or persistent weakness should be discussed with a clinician.
Severe muscle injury is very rare. Rhabdomyolysis can damage the kidneys and requires urgent treatment.

🚨 Symptoms you shouldn’t ignore
Seek prompt medical advice for unexplained severe muscle pain or weakness, especially with fever, unusual tiredness, or red/brown urine. Yellow skin or eyes, severe abdominal pain, or signs of a serious allergic reaction also warrant urgent evaluation.

Most important: don’t stop atorvastatin on your own because of a social-media warning. If you’re experiencing side effects, a doctor or pharmacist can assess whether they’re related to atorvastatin and whether a different dose or cholesterol-lowering treatment would be appropriate. Statins remain an important treatment for people at sufficient cardiovascular risk.
