Statin alternatives

Due to a 70% blockage in my LAD I had 2 stents inserted. I had no symptoms. I was put on Rosuvastatin and after a year of 5 mg was trying to increase. My statin levels were not at the level the cardio wanted. BUT they wanted me at the level as if I had had a heart attack. When trying to increase I went to feeling a few side effects to becoming a person who thought twice to climbing stairs and working out due to hip, back and leg pain. Foggy brain a bit too. Rosuvastatin was my third try of a different statin. I had border line high cholesterol before statins. So my question is, has anyone who has not had a heart attack but has stents just gone without a statin. I am sure my cardio will treat me like I am crazy to not take them, but what is worse, sitting around because you hurt or being active and happy.
