Magnesium citrate symptoms and conditions

I am a 60 yr. old woman and was on simvastatin for several years before I realized that all of my aches, pains, and muscle weakness could be because of it. I stopped taking it in March, and had very little improvement until June when I started taking 100 mg CoQ10 twice a day. I am now pretty much pain free but the muscles in my thighs are still very weak, and I am still very fatigued. Anybody have any suggestions?

Has anyone had any eye twitching? I had Mirena inserted early December. In addition to the swelling to which I looked like I could burst (eyelids included) I've had an eye twitch for the last 6 weeks.
