I am a 46 y.o male who started taking Simvastatin almost 8 months. At first I had no problems. I am an avid swimmer who swims laps at least 3x a week and had a weight lifting program (light wghts./ numerous repetitions. About 2 months ago I got severe pains in my neck and shoulder. I thought maybe I was overdoing it so I ceased workouts and went to the chiropractor. After two months of misery and missing swimming I decided to look into the statins. I am going off it tomorrow and will see if that does the trick. If I cannot exercise and be fit the Statin is not going to be useful anyway. I have a feeling stopping will help because rest and treatment sure didn't. I will try and report back
