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!!
Hello, You can do gardening with shoulder pain. But I will advise you to do in multiple breaks. As you may not be habitual with this work so the pain comes. Usually, when people don't have the habit of doing certain work and when they tend to do it leads to DOES (delayed onset muscle soreness). So you should do less work and make it a habit.  Regarding the shoulder pain, I will advise you to do shoulder exercises by which you develop some endurance which can help you to the job with ease. In my clinical practice of over 12 years, most patients who are doing a job once in a while I advise them to do in multiple breaks and also take sufficient rest. Meantime I even advised them to improve the endurance of the muscles so the pain doesn't bother much. Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.
