In 2002 I was on Lipitor for around two and a half years, my muscle deterioration was so bad, fatigue, weakness, ED and joint pain. Doctor took me off and put me on Welchol after about two weeks I felt so much better, continued on Welchol up until about three months ago and stopped, muscle pain was two much, joint pain, butt muscle pain, tail bone pain, no ED, just fatigue, just went back to the Doctor and I told him I quit taking Welcho he was mad, states no side effects, he prescribed sleeping pills and I will try Welchol again. I am 47 now and also have developed a severe case of ringing in my ear.
