Welchol and blood stream

I decided to read about side effects of Welchol. I just got back from the doctor's and she gave me some free samples of this. In the past, I had been on Lipitor and Zetia but had terrible back, hip and leg pain. I went off of those and I was fine. Started on Crestor- same pain in back, hips and legs. Now my doctor says that Welchol is not absorbed in the blood stream so there should be no side effects- only possible heartburn. After reading all of these side effects that everyone is having on Welchol, I am not going to even try it.
I am going to record everything I eat and try to control my cholesterol with a good ,healthy diet. I also have heard that Red Yeast Rice- available at GNC or Health food stores can lower your cholesterol. I might try that but for now I'm doing the healthy diet and exercise.

I have been on Welchol about 21/2 months. I have bloating and lots of gas.indegestion, acid reflux, headache in back of head. I thought was a sinus headache. Not sure now. Just called my Dr. about blood work after reading all remarks.Watch out for the other drugs, especially Crestar. My muscles were breaking down into my blood stream with that and I had to go through some painful tests to make sure threr was no permanet damage. Zocor,Mevacor,Lipitor all caused muscle weakness as did all of the statins. So please get to your Drs. if you experience any of these.
