Pravachol side effect?

This is the 3rd try on different doses of pravachol. Each time I have had different amounts of pain and memory loss. Just started again last week after a few months off and I'm having mild muscle pain and I am having bladder control problems. I had them before but did not realize they might be from the statin. However, there was no problem for the many months that I was not taking it and now it has started again in the week that I have been taking it again. Now I see the connection chronologically. I can't find anything on the internet about it. There are muscles in use to control bladder so I imagine they could be affected. Has anyone heard anything about bladder problems connected to statins?
