I Have Had Rotator Cuff Injuries In Both Shoulders. Recently,

I have had rotator cuff injuries in both shoulders. Recently, I have had pain in my shoulders that spreads to my biceps and my clavical areas. I just came off Lipitor and had muscle pain related to it. I saw my doctor recently regarding the shoulder paid but I am wondering if it could be a sign of heart problems. I am a white woman over age 68, 5 ft 4 inches and weigh 167 pounds. I have been losing weight, down from 183 or so.
