Edited to add. I see in another post you are wondering if statins are causing your aches and pains.
This article explains that your Dr. can do a CK blood test to see if it is the statins.

Muscle effects
Statins can occasionally cause muscle inflammation (swelling) and damage. Speak to your doctor if you experience muscle pain, tenderness or weakness that cannot be explained (for example, pain that is not due to physical work).
Your doctor will carry out a
blood test to measure a substance in your blood called creatine kinase (CK), which is released into the blood when your muscles are inflamed or damaged.
If the level of CK in your blood is more than five times the normal level, your doctor may advise you to stop taking the statin. Regular exercise can sometimes lead to a rise in CK, so tell your doctor if you have been exercising a lot.
Once your CK level has returned to normal, your doctor may suggest you start taking the statin again, but at a lower dose.
