question: I had already experienced what I would describe as lethargy, which I attributed to the Atorvastatin (generic), and then as a gardener with already-weakened shoulder muscles stressed from a thyroid condition (treated) , experienced extreme/throbing pain and weakness for several days after a gardening episode where I had used my shoulder muscles!! I thought, Have I hit a wall where gardening is becoming out of the question? I took magnesium, CoQ10 and B complex supplements, which I think brought me relief! Phew!!
