my father takes lipitor and i help manage his meds. there is nothing noted that says it causes high blood pressure on the paper that comes with his medicine. it says it can cause muscle pain and weakness, and nausea/diarrhea. stress can cause your blood pressure to go up, i do know that. we all have stress, but it is important to be able to handle it. some people use yoga, prayer, meditation, or things like that. i use physical labor - cleaning out closets, running, weeding the garden, etc. i also heard that holding a purring cat lowers your blood pressuer. call the doctor s office and ask to speak to a nurse, then tell her/him what your blood pressure has been. they may want to see you sooner.
