What Causes Muscle Pain While On Statins?

Question: Hello, I am a 64 year old healthy male. For more then 25 years I have been taking statins for high cholesterol, lipitor and others however now I am using repatha injection once a month to keep my cholesterol low. Now over the course of these years I have had muscle aches and cramps primarily my shoulders and it seems like muscles around and under my shoulder blade. Since I started the repatha it seemed like these aches were less but now it bothering me all the time. At one time during the course of my life I was
getting Shiatsu massages 3 times a week, and I could feel
pain when I was massaged and these helped it felt better until the next time sometimes a few days later. Now when I go for a massage its sort of strange its like my muscles are numb and I dont feel much pain but it does help. I can feel that there are like knots in different places on my back and they come and go? I am right now taking magnesium that is supposed to help but its to soon, I have been taking it only a few days with no noticeable improvement. I still am suffering sometimes no muscle aches for days and then days that it goes on day after day. I just suffer with it.
Its not debilitating but very annoying. ??? PLEASE HELP

Dear Dr. Partap, Attached are test results since 2015 to april of 2017

As you can see in the test of 10/22/2015 that is when I went off the statins
for a month and so the test shows a 100% increase.

Also all of these blood tests are done very correctly on empty stomachs for more then 12 hours and very good doctors and lab at cedars sinai hospital in Los Angeles California.

Remember I have been taking these statins for 30 years.

I notice after a hard massage it feels better but seems to always come back?
Always it seems to come back in the same places or very near. Only in my shoulders and back near shoulder blades and running down my back on the left and right sides.

I await your response

Your help is greatly appreciated, best Regards, XXXXXXX Hershman
