Nana,
Good Morning ! I have not taken Novasc (amlodipine) but use a beta blocker which is in a different class of drug from what you are using. However, often: dizziness; palpitations; muscle-, stomach- or headache; dyspepsia or nausea are side effects of amlodipine.
If your sx continue you may want to check with your Dr.
Happy Wednesday to you !
