I have had excessdive intestinal gas for the last few months since my cardiologist increased the lipitor fron 10mg to 20mg! I have a long history of CAD and in May 2006 had a double bypass (CABG) Also notice weakness in my knees and legs. I am a great walker and never had these problems in the past. I now exercise my limbs before going out... but it is the excessive intestinal gas that is getting on my nerves, to the point I hate to go out as it just comes out without warning. It is very embarassing,and thought that perhaps the increased Lipitor was the culprit.However my cholesterol is now within normal limits, and the cardiologist is happy!
