I have nausea and a stomach ache for almost a year now. I am on amlodipine and losartan meds for high BP. My amlodipine was cut in half because of dizziness. I have an appointment for a physical next month but would like your opinion. Is it one of my meds causing this daily nausea and stomach ache? Should I ask my doctor for any special tests when I see her next month? Could I have an ulcer?
