... been experiencing terrible weakness in the last 2 months or so. He started the Norvasc in November of 2009 and the Cardura in March 2010... could the combo of the 2 be causing this weakness... his legs are also terribly swollen as is his ankles and feet ... I feel the Norvasc is causing the weakness and the swelling. I want to know if I should wean Dad off the Norvasc... my father's overall health for his age is good. Your ideas?
