I had been on simvastatin a couple months when the debilitating fatigue started. Since I have hypothyroidism I blamed it on that. The fatigue got worse along with severe depression, brain fog. Numbness in my hands and feet and kidney pain kept me up at night. And then the shoulder pain started. It was excruciating. While pulling a dress over my head, my shoulder literally blew up. Turns out my biceps tendon rupture and filled my shoulder joint with chunks of cartilage. After looking at my MRI the orthopedic surgeon said if I didn't have surgery, the excruciating pain would only get worse and I'd lose the use of my arm.
Now, after stopping simvastatin my LDL has gone up to 300. Dr. wants me to start Welchol. After reading the side effects on this site....um...I don't know.
